Session C6: Military PNT Equipment: M-Code Receiver Systems 2

Technical Advancements in Dismounted Assured PNT: An Overview of DAPS GEN II
Carol Politi, TRX Systems & TRX Systems Team
Location: Ballroom D
Date/Time: Tuesday, Jun. 3, 11:10 a.m.

TRX Systems launched the Dismounted Assured Positioning, Navigation, and Timing (PNT) System Generation II (DAPS GEN II), a PEO IEW&S Program of Record, into production in April of 2024. The program reached full rate production in August of 2024. The TRX DAPS GEN II enables dismounted Army forces to shoot, move, and communicate in GPS-challenged environments. DAPS GEN II assures PNT through integrity checks of, and access to, multiple size, weight, and power (SWaP) constrained PNT sources. This presentation will review DAPS Gen II assurance capabilities, configurations, production status, and agile development and sustainment approach.
The following topics will be addressed:
• Beyond M-Code: Review of DAPS GEN II’s multi-layered approach to position and time assurance leveraging M-Code GPS, secondary satellite, multiGNSS, inertial sensor, and precision clock technologies.
• Design and Operational Flexibility: Overview of hardware and interface design, and review of use cases supported including Nett Warrior/ATAK, standalone operation, and wrist wearable capabilities.
• Production Status: Description of generally available production configurations as well as available logistics and maintenance support.
• Test and validation. Overview of innovative test-fix-text approach, rigorous test and validation process, and review of tested performance in degraded and denied GPS conditions.
• Agile approach. Identification of capabilities and features delivered through agile capability insertion.
TRX’s objective has been to deliver robust, military hardened, high performing assured PNT capabilities into production to support the Army DAPS program within a year of the Program of Record Award. That objective was met. Building on M-Code GPS as a foundation, TRX DAPS GEN II integrates additional layers of PNT technology, enabling it to deliver continuous and reliable PNT information to warfighters, even while under threat. By continuously cross-checking data from these and other inputs, TRX DAPS GEN II monitors PNT source integrity, eliminates compromised sources, and delivers assured position and time to the warfighter.
The TRX DAPS GEN II approach to fusion, the sensors and secondary signal used in DAPS GEN II, and the performance in denied environments will be presented. Physical DAPS GEN II devices in standard production configurations will be shown.
