Exelis has finished its factory acceptance evaluation work on a simulator software program that designed to replicate signal movements of GPS navigation satellites in space.
The GPS III navigation payload will be installed into Raytheon’s GPS System Simulator that is set to be integrated into the U.S. Air Force‘s operation control system, Exelis said Monday.
Raytheon subcontracted Exelis to design software for helping satellite controllers locate GPS constellations and to receive navigation data.
“It provides simulation data representative of multiple GPS III space vehicles at the level needed to support control segment test events, mission rehearsals, and anomaly investigations,” said Kevin Farrell, general manager for positioning, navigation and timing at Exelis Geospatial Systems.
Farrell added the software is intended to help ensure the OCX control system is running properly before space launch.
Exelis is also developing data encryptors that work to securely exchange data between space and ground components of the system, as well as receivers designed for monitoring stations on Earth.
The company intends for the operational control segment to help users monitor and control air traffic, forecast environmental shifts and trends, increase crop yields and help Air Force Space Command with its interoperability, accuracy and anti-jam requirements.
