Assured Positioning, Navigation and Timing (PNT)
Abstract
The Assured Positioning, Navigation and Timing (PNT) project funds the Resiliency and Software Assurance Measures (RSAM) which provides increased capability and situational awareness for fielded legacy military Global Positioning System (GPS) receivers supporting systems and soldiers through at least 2035. Legacy GPS receivers targeted for RSAM enhancements, include but are not limited to, 226,000 Defense Advanced GPS Receiver (DAGR) and 200,000+ embedded Ground Based-GPS Receiver Applications Module (GB-GRAM). RSAM software upgrades mitigate threats to legacy DAGR and GB-GRAM Selective Availability and Anti-Spoof Module (SAASM) based military GPS receivers. RSAM provides an interim solution in a GPS-challenged operational environment until future Positioning, Navigation and Timing (PNT) solutions are fully deployed. RSAM will coordinate integrated software testing with military system managers and the test community to validate software and synchronize RSAM deployment to the user. Additionally, the Assured PNT project supports the Alternative Navigation (ALTNAV) capability that will provide positioning and timing information for navigation for the Army, which completes critical timing and equipment upgrades, and key certification activities. These connections, upgrades, and certification activities are critical to operationalizing ALTNAV as an effective and suitable contingency source of PNT data in the event GPS is denied. There are no Base funds for project Assured PNT (ED5) in FY 2023. RSAM is transitioning into fielding and sustainment. The ALTNAV ground segment efforts for FY 2023 will transition to Area Protection & Alt Nav Technology (BV4).
