The GPS quandary
The Global Positioning System satellites aren't new but they certainly have gotten their share of bad publicity this year. Most recently the Air Force had to fix signaling problems with a new GPS satellite, rekindling the flames of a congressional report in May that said the current GPS satellite coverage may not be so ubiquitous in the future. According to that report the Air Force has struggled to successfully build GPS satellites within cost and schedule goals; it encountered significant technical problems that still threaten its delivery schedule.
