Lockheed Martin has received a contract from the US Air Force’s (USAF) Space Command Space and Missile Center for support and maintenance of the global positioning system (GPS) ground control segment.

Under the terms of the $104m contract, the company will provide organisational and depot sustainment support comprising of support for command and control ground systems, systems engineering, hardware and communications engineering, space vehicle and ground equipment simulation, as well as software testing and hardware maintenance.

"Sustainment activities as part of the contract are scheduled to be carried out from January 2013 to June 2019."

Lockheed Martin Information Systems & Global Solutions-Defense Space & Cyber vice president Rob Smith said: ”We’ll mirror our past successful performance to ensure that GPS continues providing reliable, worldwide positioning and navigation services to meet the burgeoning demand from strategic and tactical users worldwide.”

The GPS ground control segment is equipped with ground hardware and software that offers command and control for global satellite operations centres’ networks, ground antennas and monitor stations, which are used to command and control the Department of Defense’s (DoD’s) largest satellite constellation.

The segment also helps the Air Force Space Command’s 2nd Space Operations Squadron in daily on-orbit operational control of the GPS satellite constellation.

The Lockheed-led team for the contract includes the Arctic Slope Research Corporation (ASRC), ISYS Technologies, Overlook Systems Technologies and Tigua Technology Services, who will conduct hardware engineering, software tests, technical order management and systems administration functions.

Ogden Air Logistics Center (OO-ALC) will deliver depot level software maintenance and test support for the programme. Sustainment activities as part of the contract are scheduled to be carried out from January 2013 to June 2019.

The GPS constellation is critical to maintaining the US space superiority and also ensures availability of accurate position, navigation and timing signals to worldwide operators across numerous domains.
