Mayflower has been developing state-of-the-art GPS Anti-Jam systems for close to 30 years. Mayflower’s Anti-Jam technology has been developed and refined over this period under numerous DoD-sponsored programs, starting in the late 1980s with an Air Force sponsored Technology Demonstration program to design an adaptive temporal filter (ATF) for suppressing narrowband jammers. Mayflower continued the technology improvements in the 1990s with multiple programs sponsored by the Army and the Navy, to design adaptive spatial/temporal filters for suppressing broadband and narrowband jammers. The current portfolio of high performance, very small SWaP, robust Anti-Jam products is the result of continuous improvements to the Mayflower AJ technology. Mayflower’s ongoing GPS AJ technology innovations will continue transform the military GPS Anti-Jam systems to our nation’s modern military needs
Mayflower’s flagship Anti-Jam Electronics (AE) product, Small Antenna System (SAS), also known as NavGuard® 500 was developed under a highly competitive program sponsored by the Advanced Technology Branch of the GPS Directorate. SAS is one of the most mature and smallest 5-Channel Anti-Jam product extensively tested by many DoD branches on many air/ ground and manned/unmanned platforms.
The Communications and GPS Navigation Program Office (PMW/A 170), headquartered in San Diego, mounted a Small Antenna System (SAS) on an unmanned aircraft, then placed the small UAV in a room lined with signal-absorbent material at the FARM (Facilities for Antenna and RCS Measurements), where it was subjected to GPS jamming signals.
Equipped with model jammers, the FARM facility was used as a stage for the “enemy” to jam the GPS signal and try to knock the UAV off course. If knocked off course, the UAV would not be able to relay critical intelligence back to the ground control station — disrupting communications among U.S. and allied forces’ ships, aircraft and submarines. In a worst-case scenario, GPS jamming could even cause UAVs to crash.
