USAF Launches Upgraded GPS Satellite

The U.S. Air Force successfully launched a new-generation GPS IIR spacecraft. The satellite, designated GPS IIR-13, will join 29 other operational GPS satellites now on orbit. Lockheed Martin, which built the satellite, has delivered eight more of these satellites to the Navstar GPS Joint Program Office to sustain the GPS constellation. The GPS IIR satellites are compatible with the current system and provide improved navigation accuracy.



GPS III will introduce new functionality, including advanced anti-jam capabilities, improved system security and accuracy, and reliability. http://www.lockheedmartin.com
