Resilient GPS-Independent Navigation for Denied Environments

TrustPoint is addressing Global Positioning System (GPS) degradation and denial challenges with our integrated, commercial Alternative Positioning, Navigation, and Timing (APNT) solution that includes a proliferated constellation of Low Earth Orbit (LEO) microsatellites to enhance existing GPS services and provide coverage in the event of an unplanned GPS outage or area denial. This creates an opportunity to evaluate how existing and planned U.S. Department of the Navy (DON) User Equipment could benefit from the deployment of this technology to enhance or augment the performance of PNT services provided by GPS. This proposal includes scope to assess the applications of DON User Equipment, and identify DON requirements for integration into TrustPointÆs commercial APNT solution architecture for future interoperability on DON UE. In addition, DON-focused reference architectures for airborne platforms will be defined, and initial Modeling and Simulation (M&S) performed to evaluate TrustPoint APNT solution availability and performance in uncontested and contested, GPS-denied environments.
