Boeing Space and Intelligence Systems of Seal Beach, Calif., has completed developmental testing of a software upgrade that is intended to increase the security of the GPS ground segment, a Sept. 28 Boeing press release said.
The Selective Availability Anti-Spoofing Module that Boeing developed with the U.S. Air Force will be an upgrade to the Boeing-built GPS Operational Control Segment that has been controlling the constellation of GPS satellites since 2007. The new software was designed to ensure GPS receivers cannot be tricked by fake GPS signals that could be transmitted by adversaries, the release said.
The software has now entered the operations suitability test phase, and it could be operational by the end of the year, the release said.
