Blog Editor’s Note: Modular open system architecture (MOSA) is key to the Department of Defense’s efforts to move toward multi-sensor PNT and away from embedded, proprietary systems that are incredibly difficult to update and replace.
This article is a good review of the many MOSA-related efforts across DOD, and some of the unclassified PNT projects underway.
Open Systems Enabling GPS Backup Technology
The Army, Navy and Air Force have all developed their own backup solutions and help service members find their way, but the open standards that make PNT possible are still a work in progress.
The 2021 National Defense Authorization Act directed the Pentagon to “mature, test, and produce alternative PNT equipment” within two years. A recently released Government Accountability Office report shows that the services have launched efforts to meet that timeline with the help of modular open systems.
