Mission info
GPS III (Global Positioning System) is the first evolution of the third generation of GPS satellites. The U.S. Air Force announced in May 2008 that a team led by Lockheed Martin had won the competition to build the next-generation Global Positioning System (Navstar) Space System program, known as GPS III.
This program will improve position, navigation, and timing services for warfighter and civil users worldwide and provide advanced anti-jam capabilities yielding superior system security, accuracy, and reliability.
When fully deployed, the GPS III constellation will feature a cross-linked command and control architecture, allowing the entire GPS constellation to be updated simultaneously from a single ground station. Additionally, a new spot beam capability for enhanced military (M-Code) coverage and increased resistance to hostile jamming will be incorporated. These enhancements will improve accuracy and ensure availability for military and civilian users worldwide.
