Five steps for choosing the best car of GPS navigation written by: Joyce Li

Views: View (s 559) as far as we know, there are many car GPS navigation units, and they are complex, so it is impossible for an unprofessional person to choose the right for your car. Then I am happy to experience how one the best car GPS navigation for in this chapter to automatically select.

So, I will show that you ask the way to configure, see build in the GPS navigation system for your car in the first part of the below information.

First of all, see you, how much you based in dash GPS system for your car, want to spend on your personal financial situation. This will help you narrow your selection, GPS systems, and a spending limit. It will help to avoid expenditure consumers when buying a GPS navigation system.

Secondly, list portable GPS navigation system functions, that you, as the United States in details, voice guidance, a small color screen, touchscreen, Assembly suction, search Bluetooth capabilities for use as a mobile phone handsfree accessories and power supply. This kind of in shock GPS navigation system is suitable for occasional use. They are very easy and will be able to help you while driving.

Thirdly, visit so many online retailers or visit a few shops nearby, as you like, to look at the available GPS navigation systems. When shopping for GPS navigation, search devices, for units that meet the criteria laid down. Write functions, GPS brand, price and GPS model name/number of each navigation unit that created the criteria fulfilled for the purchase of your new GPS navigation system.

Fourthly, a major disadvantage of the in-dash-GPS navigation system is the lack of an internal compass, accelerometer or a device used to measure the speed. Without this feature, it is not as accurate as a build-in GPS-system when the navigated there is no GPS signal. If you live in an area where there many tunnels, skyscrapers or the GPS is used very often, it is important to buy a more complex portable GPS system, which has a build-in accelerometer.

Finally, decide which GPS system you buy, are based on price, features, and your hobby. Then you buy the system unit of GPS navigation on the store or online retailer.

This technology was originally developed by the American Department of Defense, for military purposes only, but today it worldwide used navigation aid which most frequently and is a profound impact on trade and civilian life.

GPS is to change our lives; It has brought us a new range of information, a new revolution in the wireless age. The technology is spreading, but a lot of people are still nothing of his virtues and capacity. We can to keep everything and everyone in transit, he can tell you exactly where you are, if you get lost, and it can run through the streets of every associated city and can even say, links, those that you never noticed before. It is soon to make worthy city maps artifacts in the archaic Museum Street.

The mobile phone is today the most used and popular GPS-enabled device. Is it not very surprising? The phone has developed over the years, to a variety of tools and features, to once unimaginable, so many devices out of date to integrate. The non-exhaustive list includes text-messaging, E-mail, Internet, music player, camera, and Bluetooth, to name a few. Most mobile phones virtually converter, calculator, calendar, timer, stopwatch and alarm today with built-in but essential applications such as unit.

GPS only added to the comprehensive utility of the phone. A cell enhanced capacity in two ways. As a GPS enabled device, it allows you to track the exact location of the phone, so you help to keep track of your love. Also makes it easier, look for the phone as lost or stolen. The other way in which it exceeds your expectations, is acting as a really trusted Navigator; Your phone whether you go the unexplored part of your city or even halfway around the world, would never, you will not show you the right way.

GPS antennas are priceless electronic gearing, but field conditions are sometimes hard and can affect them adversely. GPS antennas are getting better and better, and you definitely get indoors, the GPS signal, but it is not always safe.

GPS antennas are devices that supports expanding the reception signal to a GPS receiver, whether it's a standalone receiver or a receiver embedded. A GPS antenna in a situation is often used, where the GPS receiver itself somehow far away from a line of sight to the sky (such as in a vehicle), the support of the GPS receiver is in the air without for be moved. GPS antenna can be purchased for a distribution of households. Versions is quite common with cheaper home.

Reception of GPS signals may be only then trustworthy, if the antenna has an open vision of heaven. Passive GPS antennas contain a low noise amplifier (LNA). When connected to a GPS, it is the internal amplifier into the GPS, which strengthened the weak signal of the passive antenna.

So if a passive antenna use? In conditions you would have the open air a clear overview of but if something, look at the sky, which means that it is installed, has your GPS receiver, in the automotive or somewhere hidden.

Of different kinds of indoor GPS antennas can be found.
Inner GPS antennas:

If GPS antennas with a GPS connected, it is the internal amplifier within the GPS receiver which amplifies the weak signal of the passive antenna.
Internal GPS antennas means that they are created within the GPS receiver itself. External antennas are an option for some models. All GPS have built over an internal antenna. The performance of the recipient is dimension in relation to the antenna (the bigger, the better).

The internal patch antenna, the conductor is a square on square piece of metal is positioned. The advantage of the patch antenna is that it again went the satellite signal faster if they lost. Maintain the face of GPS units for best efficiency with internal patch antenna to and parallel to the Earth.

The second type is internal Quad Helix a pole with wire is wrapped. They are particularly sensitive to GPS signals. Maintain for best efficiency the GPS in the order, that the antenna to the sky shows.

External GPS antennas:
Extern means that it is not built, in or on the GPS receiver. External GPS antennas are useful if the GPS in a place, where the view of the sky like a car, boat or an airplane is blocked.

Reradiating GPS antennas:
I f the GPS receiver has not connected socket for external antenna should you use a reradiating GPS antenna, including two antennas: receiving the signal from the satellite, and the other is connected to the first and is located close to the GPS receiver. The effects are connected to the GPS receiver as an external antenna.

A technique in our increasingly wired world of the 21st century, which allows us to these challenges is GPS. A GPS-enabled device built into an ambulance can on the ambulance driver and crew not only directed by the place where the stress call been made, but would identify also the shortest route to their destination.

The next medical facilities available for the patient to recognize a costumed GPS device with the correct uploaded data. In addition, it can advice the ambulance crew with the detailed functions of various hospitals and clinics, allowing them to choose medical facility, from the appropriate services for the patient.

Ways in which GPS advantageous for emergency services can be, is fleet management. A full-featured GPS system can provide a minute by minute update the location of each ambulance back to the base or the control center. This enables better monitoring of the fleet, and makes it possible to keep every ambulance in the area a close watch on. With the help of GPS, which the caller informed the Centre with the progress of the ambulance to can help most people stress situation find scary in when ever an emergency call is made.

Slowly but steadily the number of GPS enabled ambulance in India grows. It is regrettable that enormous costs for the full adoption of GPS by ambulance acts to slow down the overall application of GPS in this area of services. Are still on local level steps is taking to integrate GPS technology in our ambulance fleets.

The Red Cross Health Department in Panchkula district updated it with 18 fleet GPS ambulance activated in November 2009. The same happened in Nagpur with 30 ambulances in May 2009 by the NMC. • the Bihar Government initiated in June 2009 to just a few examples to give a pilot project with 10 ambulances.

Today, the most efficient use of the spectrum of the world has seen more than a billion people per benefits. Two billion morning when modernised and interoperable GNSS is real. This massive installed base is an innovative advantage, and with good will of inestimable value for the United States.The the latter arises from the high degree of confidence in the United States and deal with GPS, one of most successful - and perhaps only - simultaneous foreign aid and national economic programs ever created.

Smooth dealers within a hedge, operate play with other people's money, billions of raids of this national resource for video on mobile phones, want to make young audiences.

The Federal Communications Commission has acted the ways, with reasonable expectations of a federal agency rules. There was early with the appearance of the LightSquared agenda, the issue of a decision to buy inappropriate speed.

It has refused, explains and show opportunities, one of extreme ignorance of the radio frequency (there are conflicting reports whether agency technical staff was always consulted by leadership prior to the accession to the LightSquared request) proclaimed was - and too clever by half. The Chairman, in the line for which was China according to rumors, was careful not to sign the waiver, but the Act of a child have done.

In this law, she ignored conflicts in two competing national policy objectives: the national space policy and the broadband memorandum. Rather than spending the time take to bring important principles in line, is the lack of its own course.

The row which got President lean out of the window, and now must find a solution, which allowed him, again before the election to crawl the Agency. Either that, or he and his advisers, including the FCC Chair will knuckle down and carry on regardless, political saving face in the short term during the national infrastructure and defensive skills.

Politicians never underestimate want to save face. In many ways, it's all what you have.

The best thing the GPS community in this quiet reloading may period is to keep the letters and calls to the Congress: the most secure and fact-based is the FCC, that the terms and conditions for the LightSquared waiver does not meet a requirement condition and withdraw the license terrestrial network in the 1525-1559 MHz band.

Advice: explore the technologies behind location-gate

For the past few months has controversy raged about the revelation, the Apple, and Google mobile subscribers able to track movements and, where it may be vulnerable to hackers and other inappropriate use stored this information in an unencrypted file to the handset. The resulting location-gate scandal underscores sometimes control the mobile subscriber information against the business goals of the dominant platform and applications providers. Immediate revenue opportunities from the Subscriber can these business objectives pursued or wider self-interest initiatives such as such as collecting data, the valuable to third parties such as advertisers or building notified subscribers Wi-Fi access point databases.

Furthermore, while much about the privacy implications was written the collection and use of information of consumers location, some articles have clear rules the technologies behind Apple and Google tracking activities. It is important to fully to explore and understand that these technology methods, and how she used from other location technologies, to correctly distinguish the threat through location write a review and to develop responses to protecting the privacy, at the same time the advantages of location based services.

Location, tracking and storage

iPhone and iPad subscribers had been previously aware that Apple has their location via GPS, because the company notified subscribers when an application needs, asked the use of GPS position to identify, and they, opt - in. However soon after able gate, had Apple's Vice President of software technology, Bud Tribble, told Congress in May 2011, that Apple also device locations over a period by using of triangulation between nearby Wi-Fi access points and wireless base stations was persecution. Triangulation is the moderately accurate way in which the mobile device measures close to nearby cell site or point identification and may signal strengthen, typically determining device location within a few hundred meters.

After this revelation was Apple's first answer, that "users are confused" and that it was simply "manage a database of Wi-Fi access points and cell towers to your current location... to help, your iPhone quickly and accurately calculate the location if requested." Soon after Apple site tracking activity was revealed, it was announced that Google was essentially the same, albeit to a somewhat lesser extent (Android phones do coordinate only the 50 latest updates and up to 200 Wi-Fi access locally stored locations), and a similar triangulation method without explicit knowledge of the participant. Google Android devices also have GPS ability.

Why, if both OS vendor embedded or used GPS in their phones, would access a less accurate location method of triangulation?

None of the companies has given an answer. We know that the triangulation method of less battery power than GPS, conservation of battery life for other uses when filling out performance holes for GPS in urban and indoor environments used. Also, in contrast to using GPS, mobile subscribers are either unable, triangulation or disable must, separately. More important is the fact that allows the OS vendor location automatically identify triangulation and monitor it during the time in the background without the knowledge of the participant, such as building and maintaining a database subscribers the Wi-Fi access points reported.

From the perspective of privacy is a dramatic difference between monitor the situation in the course of time (the bread crumb trail, that Apple and Google used), the position for a particular purpose and handle the location information only within the limits of a secure wireless network. Useful applications that are accepted as such as E911 situations, safety-of-life, General, deal with the latter method.

Other players in the mobile ecosystem, such as for example wireless network operators subscriber information location, as well as put together have to save files in the same way that Apple and Google have but not through it into the device as historical. Some information on the side of the network in connection with billing records for calls (also known as detail records or CDRs) is present, but this is not bread crumb track of cell IDs. E911 calls records that never one for the use of public agencies, but most users E911 call. Contains other messages, rough location may be on a temporary basis (such as location updates field) available, but these are usually not aggregated or stored for later processing.

Advice: Happen epic - Europe PNT Industry Council

We have the United States GPS Industry Council, the Council of the Japan GPS, Korean GNSS technology.

All that is missing?

The only large area without a uniform industry nexus, where can such challenges is the challenges for the community, based inter alia on GNSS performance, navigation and timing (PNT) are always more numerous and complex, and Europe. However, this is to change.

Out of my background and current activity as CEO of DW International have a standalone navigation consultancy with a strong interest in GNSS specifically, I started the European PNT make industry to trade Council (EPIC) with other industry leaders as the focal point for the PNT community concerns and to help to coordinate the effort of standardization and harmonization. In addition, it is issues such as the LightSquared debacle threatens key, that the parties in Europe have a voice on the international stage.

A recent study, carried out the emerging epic together with Marketing Analytics the need for an organization such as EPIC. We asked PNT key figures around the world on the issues relating to them and how should addresses these concerns by EPIC. For such a diverse group of respondents (including representatives of transport authorities, academic institutions, OEMs, independent consulting firm, land survey companies, maritime, and aviation) there was clear agreement on the need for a European place PNT facilitating better interoperability and harmonization of standards among the current PNT activities, carried out all over the world. Sixty-six percent of respondents wanted an international forum for the exchange of information (i.e., ideas, best practices and teachings) where such issues such as interoperability and harmonisation can be treated.

63 Percent questions as a very important issue for EPIC rated PNT system-level, although with 56 percent for PNT standards in the areas of air, rail and E112 evaluated as very important. There is no shortage of problems to tackle, and EPIC is as a major player in the formation of coalitions that are required.

As a respondent, its priorities PNT policy asked:

Galileo launch schedule; information about GLONASS L3 and GLONASS CDMA compass CPII and CPIII plans, particularly the ICD and the frequency of the scheduled L1 CDMA signal signal information and operational plans;SBAS plans, such as EGNOS and GAGAN.European regulatory plans, which aim for navigation and location; E112, road users charge tracking and logistics;Standards for navigation and location of applications and applications that use a position.

What the attractiveness of a forum for the exchange of technical know-how among experts, it was also clear that the respondents epic to act as well as wanted. You wrote:

"EPIC must result/results oriented, and not in a talk." "Therefore issues such as LightSquared set up head, so that bureaucrats listening, the science behind the decisions and guidelines as a commercially operated for the short-term political expediency."

In fact, EPIC joined the choir of the organizations, directly to the FCC call for a rethinking of the LightSquared output.

Personally, I think that with industry active in the United States and Asia, EPIC is the third leg of the stool. PNT is that large international organisations risk lagging, except where their interests are represented such a dynamic world, with so many moving parts, and the information they need, is in a consistent and practical way.

But more than that, PNT is a utility that be protected must be maintained, improved and used. EPIC makes sure that those who want to can.

It is. The participants are there. It is happening.

Advice: Cloud-based location changes enterprise field

New technology and mobile operator openness now provide real time access details on phone location for the company with no application on the mobile device required.

Yes, that's right: the application required! Cloud-based situation, offered through direct connections to wireless operators, is changing the playing field for companies to introduce immediate operational efficiency. Able to marry insight offers privacy control and flexibility, cost savings and time-to-market benefits company multimodal communication over network application programming interfaces (APIs). Whether providing geo-targeted offers, services, review the activities of workers or other location to perform delivery, relevant actions companies now cross-carrier access to site information for more than 85 percent of U.S. wireless subscribers have immediately!

This allows app-less go the company without costly and time-consuming deployment and maintenance of cell phone applications. In addition, no special hardware is required. Location by carrier networks ensures secure and tamper-resistant delivery site information, because no potentially hackable client software in the production or delivery of this information is involved in. It comes directly from the carrier network through secure connections.

Cloud-based deployment, such as on the location platform, TechnoCom opened location intelligence to all types of devices, including smartphones and feature phones. This is a major barrier that exists with the existing Smartphone only applications and allows companies, their workflows and business processes that the real time starting point for a secure knowledge and adapt immediately take advantage of reliable source. Development cycles and costs are a fraction of the required for Smartphone applications, such as download droid or iPhone apps, and the adoption hurdle of user's initiation is eliminated.

Simplification of access and the provision of paving the way for the introduction and finally opens the floodgate for location based services are implemented in all wireless networks on a large scale. The turning point is this, that cross carrier text had acceptance messaging access and interoperability on cellular text messages in the 1990s.

Through the use of technology, much like in the carrier networks and proven for use in an emergency 911, benefit companies immediately when new data become available from wireless operators, such as device capabilities, presence, tariff-plan status, roaming status, etc. Companies can necessary, immediately use this insight with upgrades to its server applications, and no new technology deployments in the field. That offers companies a huge return on investment, even integrate and consume extensions dynamically. Location from the cloud opens up a new, instant intelligence border that use not for business was possible only in the last year.

This unprecedented access to location information has a responsibility for compliance with the industry recognized privacy of controls. To do this simply to companies that are not experts in such a policy, TechnoCom offers location platform approved airline data protection management features, and we work hand in hand with our customers, to ensure that their implementations in accordance with the recommendations of laid down CTIA.

Development situation of other media such as VoIP, will further increase access Wi-Max, NFC, Wi-Fi the ubiquity of cloud-based location. As devices become smarter and more powerful, better communication and device intelligence companies are positional awareness to the yet another level of efficiency when interacting with their mobile users, workers, and the assets to catapult.

Mario Proietti is co-founder and Chief Executive Officer of TechnoCom Corporation and a member of the Editorial Advisory Board of GPS World magazine. He has a master's degree in electrical engineering from the University of Southern California. TechnoCom provides cross-carrier location services company due to its location platform Web services APIs. The company also wireless networks, products and software location integrates technologies and works to enable wireless operators E911 with location based services.

Locata: A new constellation

"GPS can develop more quickly enough." Satellite-based systems maintain that now for the can not speed of development, hyper fast evolutionary step of modern applications and devices required. "To position, for the future very become clear that GPS is now a terrestrial component."-by prospectus Locata Corporation

 

"Billions of dollars to try a large number of companies and engineers to improve the GPS in urban and indoor applications have raised," explains co-founder Nunzio Gambale Locata Corporation. "In view of the technological Locata has something completely new: the possibility of a GPS-style to create system independently on the ground."

Of the GNSS community see for themselves even to the Locata coming out party in the ION GNSS 2011, including the publication of a Locata signal interface control document (ICD). GPS world has an advance on the technology in a June the demo, which can see all ION participants. This article provides these reports to an overview of the technology.

The key to the Locata of the positioning system is the signal of the Locata transceiver or LocataLite, its time to synchronize other LocataLites on a network. Locata created a network that "is a near perfect synchronization according to the company," without atomic clocks. Each transmitter synchronized dynamically says with Locata transmitter with a patented method called time-loc Gambale, a Locata to disable network with currently about 2 nanoseconds.

Each LocataLite base station has a continuous series of approximately 10 km, much like a cell phone tower with indoor signal.

The company stresses that its transceivers are not Pseudolites, but also devices, to create the synchronization of TimeLoc, and thus enable an autonomous synchronized network that looks locally, such as GPS. The local constellation is under local control and can therefore for use to any frequency or a density needed be designed by an application makes.

The networks can scale easily. The term "local" can mean a room or warehouse (100 m2), a campus or open cut me (tens of km2), an airport terminal area with approach and landing routes (100 s km2), or a WAN, area or city (thousand km2)

Gambale sees markets for Locata of technology in defense, mining, emergency services, construction and security. An another constellation is used to integrate with existing technology, as simply Locata. This means that a Approprieate GPS Locata receiver the satellite signal when outside of the area can use a Locata network. With a combined GPS-Locata-chip, the LocataLite appears as a satellite.

The company sold its first Locata network in July of 2005. Locata signed partnership agreements of various kinds with Leica of Geosystems and Newmont Corporation (mining), the United States air force, the advanced navigation technology center at the air force Institute of technology, and several other companies under confidentiality conditions. Was a first test deployment to the Hollandia Oman Air Force base in May 2008 both truth over a test range from approximately 52 15 kilometers.

For high-multipath environments like indoor and storage, the latest development is a TimeTenna that will show it in ION-GNSS referred to a new antenna.

Future research and development focus on the miniaturization of the recipient Locata. Started first in commercial and industrial equipment, and finally in consumer devices has such as mobile phones can be integrated on a combined GPS GLONASS-Locata-chip.

Locata plans, with integrators only, not with end users to make the technology of qualified partners, the development of recipients and applications to work. The ICD is the first step in the Locata technology rollout.

The system: 2 sector takes over second IIF


Command and control of the second passes GPS block IIF by Colonel James Ross, 50 space Wing Commander, Lieutenant-Colonel Jennifer grant, 2nd space operations Squadron commander.

 

The U.S. air force 50 space wing 2 space operations Squadron took command and control of the second block IIF GPS satellites on 19 August. SVN-63 (PRN 01) healthy set on 23 August.

The 12 next-generation GPS IIF-satellites from Boeing built have improved accuracy through advanced atomic clocks, a longer lifetime than older GPS satellites and a new signal, L5, which will benefit from civil aviation and safety-of-life applications.

Missile systems Center GPS Division in Los Angeles air force base and the space remained in the control of the satellite in a 30-day in-orbit check-out time before hand out.

Constellation is more robust and powerful than at any other time in history, said the GPS wing. Members of the 2 sector operation the largest Department of Defense satellite constellation on the master control station and a worldwide network of stations and ground antennas.

II part A mandatory recalls. Air force officials want only for the second time in a quarter-century back to Active status to convert a disused GPS satellites. 2 Sector employees in late noticed can, starting the clock on the GPS IIA was SVN-30 to malfunction. Engineers and counterparts Boeing and Aerospace Corp. 2 sector developed a plan to SVN-35 in service to replace the ailing bird. The 18-year-old satellite was provided from active service in 2009, make room for the actual deployment of the latest GPS Block IIR the vehicle out of service; However his navigation signal continues to function properly.

"We in-orbit spare parts hold for exactly this purpose", said Lieutenant-Colonel Jennifer grant, 2 sector commander. "The flexibility, replacements like this with minimal impact to the global user the robustness of our current constellation and the recent completion of the expandable 24 provide architecture us perform."

OCX hits bump: no preliminary examination pass design

The the recently completed first preliminary design review (PDR) were the next-generation GPS ground control system (OCX) led by prime contractor Raytheon does not.

Not passed this critical PDR control, as early in the OCX process and in the current fiscal environment (Congress has cut budget and move elements on the right to modernise already are.), is a blow for the GPS modernization efforts. It adds the concern about the OCX GPSIIIA gap with GPS IIIA produced with the Lockheed launch space vehicles (SVs) and payloads, which are planned to start a full SS-months before the OCX-ground system was originally planned, can control to the start.

Undoubtedly, this timeline extends to the right with this development.

The PDR is a formal control by the Government adoption agency - GPS Directorate of the air force in this case - of the overall architectural design of ocx automated systems and the related C2 software. PDR, critical for military projects, is carried out mainly for the new GPS ground C2 system, to achieve confidence, that the design meets functional and nonfunctional requirements and meets with the General enterprise architecture. Overall project status, proposed technical solutions in the PDR determine developing software products and all associated documentation at a high level itself are completeness and coherence with contractual standards. The PDR is used also increase and to identify any technical and/or project-related problem solving and project, technical, safety, and/or the business risks reducing further detailed design and development, testing, implementation and operation and maintenance functions.

During a PDR, the Government has usually several options on the result. It can be:

ApproveApprove ConditionallyWithhold ApprovalDisapprove or error the program.

In this case, the Government has permission deny and not approve conditionally or formally fail until all PDR action items are checked.

LightSquared errors

For the first time in a few months, there is little of concrete messages report on this subject - as the press date August 24. The Federal Communications Commission weighs its options and questioned the additional data requested it: the number and the service life of the GPS receiver, which will be disturbed, and the number of the terrestrial base stations LightSquared plans provide.

See top story and today's news, also the navigate, survey and GNSS-design & test e-newsletter for latest developments.
Here are the highlights from the "LightSquared-watch"-Webinar on 18 August; Download at www.gpsworld.com/webinar:

GPS is probably the most efficient use of the spectrum, the world has ever seen; almost a billion people benefit, the GPS signal, which is now available. This usage is a large installed base and source of the innovative advantage for the United States. Most importantly, it provides a high degree of confidence in the United States and their maintenance of GPS.
-Scott misinformation is speed widespread and action pressure prior to analysis characterized the early stages of this process. History has been interpreted, and fit the facts distorted to desired reality. We have heard that lawyers supported allegations against the decisions of the engineers - with only the latter of verifiable data.

Microtechnology is growing up

The size of an Apple seed: Micro PNT goal (conceptual illustration), a chip timing and inertial measurement unit, 8 mm3.

The aggregated DARPA Microsystems technology for positioning and navigation timing (micro PNT) program pursues a new wave of innovation, the again and again life revolutionary ideas and fabrication technologies for micro/Nano/Pico/Femto/Atto scale packaging, ultra low power electronics, innovative algorithms, never explored architectures and use the new integration paradigms.

 

After over two decades of harmonious investment in development, potential users of so-called small technology for positioning, navigation and timing (PNT) applications increasingly questions, "we still there?" Clear, made some significant progress, and we see a footprint of the technology in a steadily-growing consumer electronics market of full interactive products of inertialen and timing of micro techniques enabled. These products include accelerometer for game applications, Gyros for car safety, resonators for watches, and more.

However, the question remains: the technology is really at the level of what we as precise navigation and timing, it is a precision of at least 10 meters in position and 1 nanosecond in time can be reached throughout the duration of the missions, ranging from minutes to hours to days? In fact technology is less adequate for many military applications perform several orders of magnitude short for long-term stability, dynamic range and accuracy compared to conventional technology, which is already known.

Why does inertial instruments and watches lead low necessarily to a reduction in performance?

We have still not even a comprehensive answer to this question, and we are still working hard to refuted the claim that the high performance micro inertial instrument is a contradiction in terms. We can make things, small, but we still they sufficiently precise and uniform; the precision Lithography-based production is the 10-2-10-3 (the ratio of the average defect to the smallest size), while the accuracy of conventional manufacturing with precision machining of two to three orders of magnitude higher, the 10-5. We know we can layer by layer with high precision will pay materials, but we can micro devices 3D really as accessible with conventional processing is easy. We have an excellent case for low-cost and bulk import consistently production, but we can challenge seriously, so-called boutique processes, when it comes to reach the precision, structural complexity and long-term stability.

We need the stability materials new knowledge about. We need also a better understanding of the material scale surface effects, energy loss mechanisms and the consequences of making imperfections on the performance of micro instruments.

PNT applications require exceptional new manufacturing technologies and new materials with special properties. To achieve the phenomenal accuracy for precise navigation and timing, we need a new wave of innovation in design and refinement of the many existing converters. Probably future breakthroughs in Microtechnology for PNT are still used on physics, new materials, highly specialized manufacturing technologies and batch Assembly techniques, selective wafer-level trim and polishing, implements a combination of passive and active calibration techniques strategically correct on-chip and introducing innovative testing technologies.

The need for advanced features

PNT-technology-use has doubled every five years since 1960, GPS and the miniaturization of electromechanical components. Future using to PNT every two years from the telecommunications, automotive navigation, robotics and other commercial markets, insert, micro electromechanical systems (MEMS) technologies, double-click. The modern paradigm of PNT is based on the assumption, allows the space-borne GPS every user on the same reference system and timing standard is available to provide the most of the time, position, speed and timing information.

Today's military systems more and more users rely on GPS, create a security vulnerability for United States and allies dismantled war-fighters, GPS or deny. If GPS is critical information regarding the position, orientation, inaccessible, and timing can be collected only by an independent integrated instruments: a local clock and two triads of the inertial sensors (three acceleration sensors for position) and three gyroscopes for guidance. The ideal solution would be a stand-alone instrument does not rely on the external. Microscale precision watches and inertial sensors are committed to the paradigm of the stand-alone PNT address.

GPS, exact positioning with integrity

31 August 2011

Brad Parkinson, the first Director of the Office of GPS joint program has a presentation, government officials and personnel to the differences between communication and navigation, to educate and why the GPS community so persistently is threats to the integrity - and why should be fought ruling in a similar way. The presentation is available here. Parkinson's disease includes includes "it is unthinkable to many, to understand that the GPS applications, and the national dependencies the the Federal Government: would seriously consider, authorize jammers that could such damage to the country."

And yet....

The presentation refers to the fact that "integrity is the cornerstone for the most high productivity applications, such as: aviation, heavy vehicle control, automatic mining, surveying, auto agriculture." LightSquared threatens GPS availability, accuracy, and, most importantly, integrity.

Parkinson continues to shed light on the difference between digital communication and digital navigation. "they are superficially similar, but there are fundamental differences that must be understood."

In digital radio communications:
Message inbound • is not known, this is the crux of the finding-
• Must determine whether any signal of "Bit" is an or a NULL
• Use sophisticated methods to resolve errors

In contrast to digital radio navigation:
Signal incoming • sequence (ones and zeros) user is completely known.
• The goal of the user is exactly the transition from one to zero (zero to one) time

Without noise, a narrow band receiver would give consistent results.  Unfortunately, the GPS band is dominated by natural radio noise. Natural radio noise caused much uncertainty in NULL crossings for narrow-band receiver

To achieve the maximum precision, has the full-band GPS receiver "sharper transitions," reduce the effects of noise and enables a more precise measurement of timing. So, the full - band GPS receiver sub-meter allows accuracy and the substantial productivity gains of the U.S. in agriculture, construction and machine control.

Why does the high performance GPS need full band GPS receiver?
Full band, improves the timing uncertainty of basic GPS measurement up considerably. This is important for the Sub meter accuracy, which is the basis for many productivity-enhancing applications with $10 billion in annual savings s credited. Full band GPS is much like a fine telescope: without full-band, the signal not well focused

Why the GPS community so immovable, additive noise (26% more noise makes) is 1 dB, is everything that what can be tolerated? Because of proposed 6dB LSQ four times the noise makes means: this relates to all satellites in view. Th result is significant damage timing the code transitions and much reduced precision. Another result might be complete loss of lock on GPS signals. It would also significantly extend the time to achieve "first fix."

With double noise amplitude (6 dB more noise makes), have full-band GPS receiver accuracy substantially impaired. A leisure-GPS users (mobile phone) some degradation could - tolerate if he can ever receive. The precision user has no such width.

Parkinson's is on difference view of distribution models to explore, and concludes: to ensure the navigation in the errors, the GPS must take the lowest damping of the interfering signal. This is in contrast to a communication Designer, who must take on biggest cushioning. Can these differences are often at least 10 times to 20 times or more

Parkinson's general conclusions:
It is unthinkable to many, to understand that the GPS applications, and the national dependencies that the Federal Government:
• Would seriously consider authorize jammers that could such damage to the country
• Make would be to prove that they are infringed, the load on the GPS community you
• Would a private company repeated its intention to change and force the GPS user community, again re-prove tolerate damage.

Our banner should "not have the availability and integrity of GPS destroy." "It is the GPS infrastructure important."

Article from 2000 predicts controversy LightSquared

6. September 2011

An article in the GPS World published September 2000 problem seems unusual looking ahead and also relevant for the current LightSquared controversy. In particular a passage reads: "with one single makes level, as the criterion for the decision on the release ignores the special features of GPS and possible future GNSS with geometry dependent properties." "Therefore, it is with a specific measure for GNSS release not recommended for other systems in this band or elsewhere."

Law in the United States applauds reintroduction of FLAIR MAPPS

7. September 2011

MAPPS announced that cadastre to inventory all federal real estate to develop make an invoice, a current, accurate Federal in the Senate, praise from the National Association of private sector geospatial companies was introduced.

The Federal land asset inventory Reform Act ("FLAIR"), was S. 1153, June 7 from U.S. Senator Orrin Hatch (R - UT) and Mike Lee (R - UT) introduced.

In a statement describing the Bill, said Senator hatch white "everyone, that the Federal Government is the nationwide largest landowners." In fact, they have more than 60 percent of all land in Utah. Incredibly, but nobody knows exactly how much the Federal Government has, because it does not hold is a precise inventory which can and led to waste and bad management. "This law requires the Government to existing technology use to this problem by developing a single, uniform, database an end set, identifying all federal property." Luke again, "it helps to know the Federal and national Governments, which are available for sale and how much energy and other resources on these companies for the development are." "It will also save to to track taxpayer money by eliminating the Government currently based more inaccurate as a result of two lavish and duplicate databases, which the real estate."

An accurate inventory of land owned by the Federal Government was recommended by the Government Accountability Office and the National Academy of Sciences. The FLAIR of these recommendations implemented, as well as calls for an inventory of the existing inventories to eliminate to save reproduction and tax dollars. In testimony before Congress in 2005 Minister of the Interior Gale Norton said the Interior Department alone has more than 100 other property management systems.

MAPPS Executive Director John Palatiello expressed deep appreciation for the leadership of Senators Hatch and Lee. "Mr. Hatch and Mr. Lee with many participants introduction of this important federal legislation work." MAPPS commends Senators Hatch and Lee and looks forward to the cooperation, the FLAIR-law to adopt, ", said Palatiello. Have previous passing of the law of FLAIR support of organizations like the American Congress of surveying and mapping (ACSM) and the national States geographic information Council (NSGIC) acquired. "The law would set a multi-purpose cadastre or an interoperable packet based geographical information systems." This is a good example of an opportunity for ' map once, use many times ', ", said Palatiello.

MAPPS members the FLAIR act in Congress promoted West during the Association programs Annual Conference, held March 15-16 in Washington, DC by meetings with members of Congress and staff. In April representatives Ron kind (D - WI) and Rob Bishop (R - UT) Companion House Bill, h.r. 1620, and the cross-party won agreed representatives Jason old Al (D - PA), Earl Blumenauer (D - OR), Bruce Braley (D - IA), Jason Chaffetz (R - UT), Mike Coffman (R-CO), Gerry Connolly (D - VA), Cynthia Lummis (R - WY) and Todd Platts (R - PA).

GPS World files freedom of information request for US gov LightSquared letters

8. September 2011

GPS world has learned that several federal agencies have official statements to the national telecommunications and information administration of the operational and economic impact of the terrestrial signal LightSquared on GPS services and has submitted, one application of the freedom of Information Act (FOIA) with NTIA, to acquire it.

A source who has seen agency letters, it is as a "very powerful", and stated that the NTIA has delivered none of the letters to the Federal Communications Commission, weigh the matter. This source the NTIA as "sit on it" as part of a "massive bureaucratic game", and further stated that Senator Charles Grassley Iowa and representatives of the Congress "always are efforts to investigate stonewalled the issue by the FCC in their".

Another source, which is dedicated in the Agency impact statements said GPS world, that the NTIA is probably a "Instructions see official reason as part of its deliberative process" to make a recommendation to the FCC. The NTIA is a co-regulator of the spectrum with the FCC, although these last have to say on this matter. This source confirms that they "see letters to the light of love for them."

The GPS World FOIA request calls "All letters by the Federal Communications Commission for additional terrestrial transmission to the national telecommunications and information administration of other agencies of the Government in July 2011 time frame for the LightSquared-waiver sent." "These agencies include, but are not limited to, the Department of Defense, the Department of transportation, Department of Homeland Security, the Federal Aviation Administration, U.S. Coast Guard, U.S. air force, the Department of Commerce, the Department of agriculture, the Department of energy, the Department of the Interior, and the Department of State."

The letters were written by the respective federal agencies in response to a may-tasking of Anthony Russo, Director of the National Coordination Office for space-based positioning, navigation and timing.

Locata passes critical design review milestone for the US air force ground-based positioning system

Prototype provides centimeter accurate positioning over large areas, if GPS is completely denied 9 September 2011 Locata

Locata Corporation today announced that it the critical design review (CDR) contract phase of an Locata network has successfully completed, with which the United States air force, a ground-based equipment, centimetre exact "truth-reference-level" positioning system for use in environments with GPS denied is. The USAF 746th test Squadron (746TS) awarded a multi-year contract for this project in July 2010, and the CDR was Locata the last milestone before the USAF required a technology demonstration in the United States to be fulfilled. Locata of non-GPS based positioning system (NGBPS) - sold as a LocataNet - provide accurate positioning when GPS jammed more than 2,500 square miles is White Sands Missile Range (WSMR) in New Mexico.

The project major milestone date, shows completion of COR, the company's detailed LocataNet design as the location of the non-GPS-based positioning component of 746TS ultra-high precision reference system (UHARS). The Treaty now moving an initial deployment of about 600 km to WSMR for further tests in October 2011.

"I am excited about the potential of Locata who has technology reference system to improve accuracy in an environment with navigation warfare dramatically our", said Christopher Morin, technical manager for the 746TS on the Hollandia Oman Air Force base in New Mexico. "The Locata team has great progress made in the last year to develop, the hardware and software to keep track of low and medium-sized dynamic flight profiles in all sections of the heights that we are the next generation systems testing the DoD navigation required." The prototype tests carried out in Cooma and reference solution, while the CDR clearly out Locata has and is successful modelling of different sensors, antenna and tropospheric errors. "I expect that the technology demonstration planned for early FY12 enter trust us to field this system throughout the region 40 60 miles from WSMR, that we use system tests for the navigation."

Locata of non-GPS based positioning system (NGBPS) illustrates this technical news, according to Locata:

Proof of the Locata autonomous, nanosecond precision TimeLoc synchronization function if Locata another transmitter (LocataLites) up to 30 miles (50 km) placed will show that TimeLoc "can be cascaded" from a LocataLite to another more "TimeLoc hop" of at least 30 miles (50 km) per hop; viewing LocataLites can successfully at the various high power amplifier to deliver much longer ranges, however, continue to exact TimeLoc transfer, show that Locata run receiver tracking loop appropriately under demanding "military-spec" speed, acceleration and jerk; Locata demonstrate receiver acquisition and tracking Locata positioning signals in the range of at least 30 miles (50 km), navigation solutions show with tropospheric models, the sufficient large tropospheric error by terrestrial signals in this range; reduce demonstrates a carrier phase "truth-reference solution for the 746TS of the development, production and new stations and aircraft antennae show features provide both satisfactory coverage of WSMR test and reasonable income and multipath mitigation for the aircraft. The new antennas antennas have been developed in collaboration with Cooper Ltd Marlow, Buckinghamshire, United Kingdom.

John Raquet, Director of the advanced navigation technology center at the air force Institute of technology and Chairman of the satellite for the Institute of navigation, the Group joined six other positioning perform experts from the 746TS Australian headquarters of the Locata vx6.0 of a four-day, performed, a careful review and analysis of real data of Locata while two flight studies on a 600-square mile LocataNet provided to Cooma airport in southern New South Wales. Was Locata produced a CDR-final report forgiven and accepted according to this analysis. Locata has now officially pointed out was that the NGBPS-CDR objectives and the CDR is officially closed.

The next step will be deploying Locata of technology in the White Sands Missile range in October 2011. The 746TS to a paper on the NGBPS program on the Institute of navigation (ION)-GNSS 2011-Conference in September in Portland, to present Oregon. The paper is the story of the 746TS positioning functions, and the financial results of relevant Locata flight tests set out.
