PHOENIX, Aug. 19 (UPI) -- Honeywell says three of its components for U.S. military GPS satellites being built by Lockheed Martin have passed a Critical Design Review.
The components were its On Board Computer, Reaction Wheel Assembly and Inertial Measurement Unit.
The total contract value for the three components for the GPS III program is more than $106 million through the life of the program, the company said.
"Achieving the CDR milestone demonstrates that the OBC, RWA and IMU have completed a rigorous design phase and utilizes the GPS III systems engineering and program management fundamentals," said Dave Douglass, vice president of Space, Missiles and Munitions at Honeywell Aerospace. "The OBC will run flight software that provides attitude, power, and thermal control for the GPS III space vehicle."
Honeywell's OBC is part of the GPS III space vehicle's telemetry, tracking and command subsystem, and provides redundant processors used through all phases of operation, including launch, transfer orbit, nominal operations and disposal.
The company said its RWA and IMU are part of the attitude control subsystem.
