The U.S. GPS satellites and ground control systems are controlled from its headquarters at Peterson Air Force Base, Colo. The Block III satellites are expected to allow military and civilian users to determine their position within 3 feet, compared with 10 feet with current technology.
The GPS Satellite
Higher-powered signals from Block III satellites are expected to be harder for enemies to jam and easier for receivers to tune in, especially in urban canyons or under thick tree canopies. The first flight model is expected to arrive at Waterton Canyon next year and be launched in May 2014.
The GPS Satellite in orbit
U.S. and other countries have agreed to make a new, common frequency available to civilians. That means civilian receivers could calculate their position from a number of different satellite navigation systems.
Inspecting the GPS Satellite
The Pentagon expects to buy and launch a total of 32 Block III satellites. The Air Force says it will cost about $5.5 billion to design, build and launch all the satellites and upgrade the ground control systems.
