“Making sure that PNT capabilities are not lost due to jamming, spoofing or other disruptions is one of DOD’s highest overall priorities. For the Army in particular it’s an enabling capability for its top six modernization priorities, according to the newly released 2019 Army Modernization Strategy: Investing in the Future.”
“Army PNT uses this approach to support development of a new PNT capability to reduce the weight, power requirements and collective space needed for GPS receivers and antennas. They also want to add enough different sources and types of PNT to these units to ensure that the capability is available to the warfighter even in contested or denied areas.”
“One of the key goals of the MAPS and DAPS effort is to be able to operate in areas where GPS may be contested, unavailable or unreliable. MAPS equipment will incorporate failovers (backups and/or redundancies), anti-jam antennas and anti-spoofing capabilities to make it more resilient. It will also have alternative sources of positioning, navigation and timing data to enable the receivers to “kind of ride through” periods when GPS is degraded and still be able to provide assured PNT, said Willie Nelson, director of A-PNT Cross-Functional Team.
“What we’re trying to do is develop alternative ways other than GPS,” Gen. John M. Murray, commander of Army Futures Command, told reporters during the Association of the U.S. Army’s annual meeting in Washington in October…
The Army also hopes the private sector can provide breakthrough technologies and has reached out through industry days and through some of its research organizations like the Army Applications Lab.”
