June 26 (UPI) -- Lockheed Martin is nearly finished with its third GPS III satellite, part of a planned order of 10 to form a new GPS network for the U.S. military.
The GPS III network is meant to provide greater accuracy for air, ground, and sea-based GPS systems. It features anti-jamming systems that are supposed to be up to 8 times more effective than other satellites. The first GPS III satellite SV01 has been delivered to the Air Force and is expected to launch in 2018.
