A Lockheed Martin-led team has tested the network communications equipment and spacecraft bus of a satellite for an Air Force program.
Team members evaluated the first GPS III space vehicle bus’ subsystems and determined they can be integrated into the satellite’s navigation payload, Lockheed said Wednesday.
The Air Force intends to have 32 satellites in orbit for the GPS III constellation.
Keoki Jackson, vice president of Lockheed’s navigation systems mission area, said the team will integrate payloads and conduct environmental tests for the program’s next step.
Lockheed worked with ITT Exelis, General Dynamics, ATK, Honeywell and other companies to test the bus’ command and data handling features, environmental controls, on-board computer and flight software and electric power regulation systems.
Exelis will deliver the navigation payload for space vehicle one to Lockheed later this year.
