U.S. government report warns: GPS constellation of poor maintenance to the verge of collapse

Traveled outside of the modern driving have become accustomed to the use of satellite navigation systems, but the U.S. government released a report warning, management by the U.S. Air Force Global Positioning System (GPS) is no longer reliable and the "near collapse" may begin to lose in the next year. According to the report, the Air Force because of serious cost overruns and technical problems, not in accordance with the established day update and send a new generation of satellite hundreds of millions of users may be affected.
According to Hong Kong's Ming Pao reported, the report written by the U.S. General Accounting Office (GAO) recently submitted to Congress. GAO criticized in the report, would be responsible for managing the U.S. Air Force GPS system since the early 1990s, has spent $ 2 billion maintenance system, but the whole system collapsed edge delay of repairs and cost overruns.
The report notes that "in recent years, the Air Force spending and plans within the deadlines to complete the maintenance task, but encountered great technical problems". A result, the Air Force in the management of the GPS system cost overruns of about $ 870 million and delay the replacement of a new generation of satellite. The report warns that the gps navigation is no longer reliable and the "near collapse", may lapse before the next year.
The U.S. government was scheduled to launch the first GPS replacement satellite into space in 2007, but not yet implemented this year, the authorities claimed that complete the launch in November this year. The report warns, the Air Force did not adopt the necessary measures to keep the system the smooth operation, is still unknown whether the Air Force can in a timely manner the new satellite into space, to maintain the current gps navigation system undisturbed.
"New Scientist" magazine, satellite navigation and GSP operation of the device based on at least four satellite signals for comparison of the locked position, at any time the system are required to have 24 satellite on-call operation. 31 satellites currently in operation, some have been "aged" over four years. GAO is expected in 2011 and 2012, the operation of the number of satellites is less than 24 opportunities for the fifth. Although this will not lead to complete failure, but its accuracy will be seriously compromised.
The gps navigation system, where failure will hinder the U.S. military developed in the field of global military map, track targets and intelligence gathering national defense. People's daily life will be affected.

Conclusion

Last year I reviewed the Gps tracker and gave it high marks. In many ways, it is a smaller, lighter, more rugged, all-around better version of the GPRS.
The most important improvements is its long battery life. Throughout my testing period. This can be stretched significantly by increasing the time interval between location updates, or by adding an optional battery pack that lasts up to 6 months between charges.
Slightly larger than a matchbox car and weighing just 76 grams, Enduro is easily carried in a coat pocket, backpack, handbag, inside a stuffed animal, or just about anywhere you can think of. Accurate to within about 15 feet, WorldTracker Enduro uses Assisted-GPS, or A-GPS, to report its location on a user-definable schedule (i.e. every 15 minutes).
Location reports are accessed via a webpage, and position information is spectacularly displayed using Google's or Microsoft's 3D maps. Date, time, speed, heading, and street address information is displayed on the map, and breadcrumb trails show the path the WorldTracker has taken.
