GPS Failure?
Tidbits are reporting on the potential for a degradation in GPS accuracy over the next 2 years. The basis for the article is a recent Government Accountability Office report on the US Air Force satellite replacement program for GPS which is behind schedule and over budget (nothing new there then for the military!). However a risk analysis is highlighting the likelihood for the constellation to drop below 24 satellites potentially reducing accuracy. And, if over runs continue, the risk of a failure of the system. Not much to do but watch and wait, but clearly it's a highlighted risk.
