Exelis completed factory acceptance testing for the Global Positioning System III navigation payload simulator software, the company said.

The software will simulate the behavior of GPS signals in space and will be used for testing the Air Force’s next-generation GPS ground station, known as the operational control system (OCX). The Exelis software will be integrated into the Raytheon-developed GPS System Simulator within OCX.

In 2010 Exelis was contracted by Raytheon to provide critical software elements in the navigation processing subsystem to enable GPS constellation controllers to better understand the satellites’ exact position, the company said. Exelis is also building high-precision receivers for use in ground monitoring stations placed around the world, as well as data encryptors to ensure secure information exchange between the ground and space segments of the system.

As part of the GPS modernization effort, Exelis is also on contract with Lockheed Martin to provide payloads for GPS III satellites.
