Raytheon has completed a series of risk reduction functional checkouts on the ground control segment of the U.S. Air Force‘s Global Positioning System satellites.
The company said Wednesday its team conducted tests on GPS Operational Control System Block 1 components with a focus on OCX software.
The test involved the integration of OCX Block 1 master control station with the GPS system simulator as well as GPS constellation management and sustainment to demonstrate OCX’s navigation and timing functions, Raytheon added.
The company also ran Kalman filters and generated GPS satellite navigation uploads during the test.
Raytheon is developing GPS OCX for the Air Force to update the availability, accuracy and security of the current GPS operational control system that provides support for the U.S. military and civilians.
The company will deliver GPS OCX in “blocks” such as Block 0 that comprises the launch and checkout system designed to deploy GPS III satellites into early orbit as well as Block 1 that is built on Block 0 and provides full OCX functionality.
GPS OCX is designed to feature modernized systems such as cybersecurity and jam-resistant and operational military code.
