​The Next Generation of Assured PNT
Picture
Export Controlled
The Most Advanced Navigational System Available for the Dismounted Soldier
Built to the demanding requirements of a U.S. Army Program of Record, TRX DAPS II is a state-of-the-art navigation system developed to replace the legacy Defense Advanced GPS Receiver (DAGR). 
​
TRX DAPS II leverages M-Code GPS and other technology layers to deliver Assured Positioning, Navigation, and Timing (A-PNT) information to warfighters and their combat systems in situations where GPS is denied or compromised.

TRX DAPS II Goes Beyond M-Code​
Non-Stop, Reliable PNT
Military-grade GPS based on M-Code technology is the most reliable source of PNT available for the battlefield. Currently, TRX DAPS II is the only proven production system being fielded to deliver M-code GPS to dismounted warfighters.
​
TRX DAPS II is much more than an M-Code receiver.  Building on M-Code GPS as a foundation, TRX DAPS II integrates additional layers of PNT technology, enabling it to deliver continuous and reliable PNT information to warfighters, even while under threat.

Multi-Layer Assurance
​
Unmatched A-PNT Capabilities
TRX DAPS II provides warfighters and their combat systems with a continuous stream of assured PNT information by fusing inputs from a diverse range of PNT sources including:
  • M-Code GPS​
  • Integrated Inertial Sensors​​
  • Complementary PNT Sources​
By continuously cross-checking data from these and other inputs, TRX DAPS II monitors PNT source integrity, eliminates compromised sources, and delivers assured position and time to the warfighter.

Diverse
Satellite Sources

With access to three available sources of satellite based PNT, TRX DAPS II delivers military-grade satellite assurance and broad spectrum diversity.

Dead Reckoning
With integrated inertial and environmental sensors, TRX DAPS II 
​enables warfighters to reliably maneuver in the absence of signals from space. ​
Picture
Timing
​Holdover
Using its internal precision clock, TRX DAPS II maintains accurate time while under threat, enabling uninterrupted time transfer to warfighters and their combat systems. ​

Threat
​​Monitoring
TRX DAPS II detects and eliminates PNT sources compromised by jamming or spoofing attacks, while alerting the warfighter to potential threats.​
DAGR Backward Compatibility
Seamless Migration to M-Code GPS
TRX DAPS II was selected by the U.S. Army to replace the legacy Defense Advanced GPS Receiver (DAGR). Using TRX DAPS II, existing DAGR users can seamlessly upgrade their existing deployments to immediately access the resilience and assurance of M-Code based Assured PNT.
​​
Plug & Play Interoperability - The TRX DAPS II solution includes a family of cabling accessories which support the standard interfaces and communications protocols commonly used in existing DAGR deployments.​
