Boeing to continue sustainment support for USAF’s GPS IIA and IIF satellites

Boeing has agreed to continue providing sustainment support to the US Air Force's (USAF) GPS satellites that are currently in orbit.

Boeing has agreed to continue providing sustainment support to the US Air Force's (USAF) GPS satellites that are currently in orbit.

Under the agreed terms, the company will support the GPS IIA and IIF satellites for the next five years.

Boeing Government Satellite Systems vice-president Dan Hart said: “This agreement continues Boeing’s strong legacy of GPS innovation and mission support.

"This constellation of orbiting satellites provides navigation data to military and civilian users throughout the world."

“We are focused on delivering reliable, affordable and resilient GPS capability now and for generations to come.”

The USAF's GPS constellation is designed and operated as a 24-satellite system, comprising six orbital planes, with a minimum of four satellites per plane.

The USAF launches the satellites from the Evolved Expendable Launch vehicle into nearly 11,000-mile circular orbits.

The satellites transmit signals on two different L-band frequencies, while circling the earth.

The 24-hour navigation services provided by the GPS include three-dimensional location information, velocity and precise time; continuous real-time information and passive all-weather operations.

The GPS IIF satellites provide improved signals for enhanced precise global positioning, navigation and timing services in support of both the warfighter and the growing civilian needs.

These satellites use advanced atomic clocks to provide improved navigational accuracy.

The longer design life and a third operational civil signal makes IIF suitable for commercial aviation and safety-of-life applications.
