Army Trains to fight in “Blinded, GPS-Denied” Environment

The Army has spent years preparing to operate in what’s called a “GPS denied” environment, meaning a combat scenario in which GPS navigation and connectivity were jammed, interrupted, hacked or simply disabled.

Mounted Assured Positioning Navigation Timing Systems

Many weapons developers have for years operated with the understanding that one of the first moves a great power enemy is likely to attempt in war is an effort to jam or disable GPS. As part of this equation, the Army and other military services have been immersed in efforts to identify alternative methods of establishing Positioning Navigation and Timing technologies. These efforts have been based upon the premise that the US military is potentially over-reliant upon GPS. Should GPS get destroyed in a war, for instance, the US military might lose navigation, targeting, communications systems and an ability to operate unmanned systems programmed to follow GPS waypoints.

How would the Army fight if it were “blinded” by a successful jamming of GPS? The service has for years now been working to answer this question, and is now making new progress through a program called MAPS, for Mounted Assured Positioning Navigation Timing Systems. The Army has just awarded a $500 million deal to Collins Aerospace for the purpose of acquiring MAPS systems in coming years. While some of the technological specifics may not be available for security reasons, an essay from the Army’s Program Executive Office, Intelligence, Electronic Warfare, Sensors (PEO IEWS) says the system introduces cutting edge “anti-jamming” protections.

“MAPS utilizes enhanced anti-jamming and anti-spoofing protections to provide Assured PNT to Soldiers on Army platforms in contested environments. MAPS distributes PNT to onboard systems and clients that support navigation, mission command, fires and maneuver,” the Army essay says.

The approach with MAPS is two fold in that it both seeks to “harden” or secure GPS and also integrate new PNT technologies able to provide non-GPS-reliant connectivity.
