APPROVED FOR PUBLIC RELEASE
GPS and other satellite-based sources must operate in contested environments. U.S. space systems have historically maintained a technological advantage over of our potential adversaries. These potential adversaries are now advancing their space capabilities and actively developing ways to deny our use of space in a crisis or conflict. While significant progress has been made in assured Positioning, Navigation, and Timing (APNT) over the last few years, acquiring reliable PNT for extended periods when satellite denied – especially over a broad area - is of concern.
One can attain an advantage in delivering assured GPS level positioning and timing in denied areas through collaboration with advantaged assets. Assets outside of the degraded environments must be able to reach in and share their positioning and timing references with assets operating within degraded environments. To support this integration of new capabilities, the PNT systems must have modular open architectures and employ standard messaging protocols. Additionally, in designing PNT aiding systems, care must be taken to ensure that these new PNT signals are resilient to improve reliability and survivability.
In a joint effort the US Army C5ISR Center and commercial partners we are working together with the objective of developing a multidomain collaborative navigation system prototype that is resilient. The design is a hierarchical, open architecture network providing network aided positioning, navigation, and timing (PNT). Modular open hardware and navigation software architecture has been prototyped on the end user equipment to support integration of network constraints as well as other new sensor capabilities. The presentation will review the prototype system and the test results from PNTAX 2023.
The results demonstrate that the approach enables both delivery of accurate and resilient PNT collaboration over large distances and meeting the SWaP and cost needs of the dismount warfighter. It enables advantaged platforms to support disadvantaged platforms including dismounts and other ground platforms by sharing PNT.
The technology developed will enable multidomain collaborative navigation between manned/unmanned platforms and warfighters. Platforms with access to GNSS signals (or simply high quality PNT systems) will be able to share that PNT information over long distances to improve PNT assurance for warfighters in contested environments. The developed capability will be able to provide additional sensor inputs to PNT systems as well as into fires platforms that require accurate PNT information in the most contested environments, and in doing so will help to improve mission effectiveness.
