Ok David,
Thank you for the link info.
Lets put the issue into some perspective.
The report stems from The U.S. Government Accountability Office (similar to our national audit office) that audits US government expenditure . As part of it's remit it reviews the effectiveness and expenditure on sponsored programmes, and the GPS is one of them.
Currently the USAF is the primary government agency that manages the GPS programme. They are responsible for developing, procuring and maintaining the system. The GAO has identified various areas of the GPS project that has not been managed as effectively as they might, and as a consequence the $2b budget for the current period may not allow the GPS system to be updated according to the optimum schedule. Basically this means that some replacement satellites are not ready for service yet.
I have found no report that states the US military is withdrawing from funding.
For best world coverage the system needs a minimum of 24 active satellites, Currently there are 28 and some were due to be taken out of service as replacements were launched, but due to delays in getting the replacements ready, there is an increased chance that some older satellites may cease to operate before their replacements are available.
The possible consequences might involve a reduction in the availability of high reliability positioning signals to the commercial market. This may result in poorer tracking at times and occasionally loss of signal.
This does not constitute nor predict a TOTAL FAILURE of the GPS. If this total failure was seen as probable outcome, there would be far more about it across all types of media. The absence of such wide spread alarm is telling.
The US government made a commitment to provide a free GPS system for the non-military market, and based on that assurance funding is made available. As a result of the GAO report, the USAF's management of the programme will be reviewed.
A multi-billion dollar world wide market for GPS based systems has grown up. This is not simply related to domestic users finding their way from a to b, but multiple other applications, which include security, road toll charging, and offender tagging as some of the national uses of GPS along with many other commercial uses.
There is too much at stake to forsee GPS being dropped. The US economy benefits from this so it is unlikely the plug will be pulled on the GPS by the US Govt.
I have found no report that states the US military is withdrawing from funding.
