Satellite Battery Modification Expected to Add 27 More Years of Life to GPS IIR/IIR-M Fleet

1/22/2014 - LOS ANGELES AIR FORCE BASE, El Segundo, Calif. -- Since October 2012, U.S. Air Force Space Command's Space and Missile Systems Center (SMC) has been analyzing, characterizing, testing and implementing modified battery charge control rates across the GPS IIR/IIR-M fleet. This fleet of 19 satellites comprises more than half of the Global Positioning System (GPS) constellation. As of Nov. 15, 2013, the USAF's 2nd Space Operations Squadron (2SOPS) completed the modification, which will extend the life of these satellites' operational capability.

Batteries are projected to be the primary life-limiting component when GPS IIR/IIR-M vehicles are past their design life. Analysis by SMC, The Aerospace Corporation and Lockheed Martin indicated that reducing the charge rates during solstice season would add an average of one to two years of life per space vehicle. SMC GPS directorate and 2SOPS will closely monitor the real-world results of this project to ensure they are in line with the expected gains. In total, it is anticipated that the modification will add more than 27 years of cumulative life across the GPS IIR/IIR-M fleet.

The Air Force Space Command's Space and Missile Systems Center, located at Los Angeles Air Force Base, Calif., is the U.S. Air Force's center of acquisition excellence for acquiring and developing military space systems. Its portfolio includes GPS, military satellite communications, defense meteorological satellites, space launch and range systems, satellite control networks, space based infrared systems and space situational awareness capabilities.
