The FAA , the administration of U.S. Civil Aviation, has published a recommendation of caution regarding a series of tests planned on the GPS system by the Department of Defense (DoD ). A first series of tests began January 20 and ends February 11 and a second series of tests will be held from February 15 to 22. The GPS could be disrupted could be on the U.S. southeast quarter, the wide geographical area being : Florida, North Carolina and South Georgia, Alabama and parts of Virginia and Tennessee.
Some forums have not failed to question loudly on such requirements, combining GPS and therefore necessarily DoD conspiracy theories. However, no mystery behind it all: no one knows precisely what are these tests but it is probably prudent to update, ensuring limited number of significant deficiencies that have already occurred in January 2010 during the previous update.
As recalled that good article, the DoD has developed the concept of GPS in the early 60s and is from an executive order of President Reagan in 1983 authorizing civilian use, also responsible for software updates and maintenance of satellites.
