Broad Research Heritage​
Over 20 Years of Program Engagement​​

Through intensive internal R&D and ongoing engagement in DoD and government research programs, TRX Labs has developed deep expertise across an array of PNT algorithms, sensors and architectures. 

No single technology can deliver assured PNT on its own. TRX’s NEON® suite of PNT algorithms were developed to effectively integrate diverse sources of position and time, delivering the optimal PNT performance in GPS-denied and contested environments. 

Engagement in Over 25 DoD
​and Government Programs

TRX’s advanced fusion algorithms and efficient design approach enables us to deliver sophisticated assured PNT solutions in very low-size, weight, and power (SWaP) packages.

Sensor Fusion
​Integrates Diverse Sources of PNT​

Sensor fusion is a foundational element of TRX’s PNT capabilities – it’s been an integral component of nearly all TRX Labs research. 
​
TRX Labs' sensor fusion implementations employ state-of-the-art navigation filters, allowing a diverse set of PNT-related technologies to contribute to the position calculation, including inputs from satellite sources, inertial and environmental sensors, RF ranging, terrain and map data, precision clocks, and integrated platform-based sensors.

Fusion of Sensor, Terrain and Routing Data to Improve Tracking when GPS is Denied​

Map Matching
Extending Dead Reckoning Accuracy ​

Since our founding, TRX Labs has been developing innovative map matching and inference techniques to deliver high accuracy positioning for users operating in satellite-denied environments for extended periods. 

Our NEON algorithms infer information about the environment from a user’s inertial motion and correlate that with terrain, building maps, or inferred data. Validated through extensive testing and applied to indoor and outdoor use cases, these map matching capabilities can significantly extend dead-reckoning performance.

​RF Ranging
Navigating from Trusted Positions

TRX Labs has developed RF ranging capabilities that enable users in GPS-denied situations to obtain position information based on the strength of RF signals received from UWB or Bluetooth beacons deployed in fixed locations nearby.   

Developments include a UWB phase difference of arrival (PDOA) beacon that can provide both range and bearing information to equipped users, enabling them to better navigate in satellite-denied situations.

Timing Holdover and Time Transfer
Accurate Time While Under Threat ​

In satellite-denied environments, warfighters can lose access to the timing data required to keep their combat systems synchronized. TRX Labs has developed timing holdover capabilities that enable PNT systems to maintain accurate timing during these denied situations. 

TRX Labs has also demonstrated the ability to transfer trusted and accurate ranging and timing data between combat systems over military wireless networks, further improving PNT assurance for warfighters in contested environments.

PNT Modularity
Integration with Other PNT Systems

TRX Labs follows a modular open systems approach (MOSA) that enables the flexible and rapid addition of new PNT sensors and capabilities.   

By employing flexible sensor fusion algorithms, standard interfaces and open APIs, TRX Labs can incorporate best-of-breed, third-party PNT technologies into our research activities. In ongoing research, TRX Labs is developing the ability to plug-and-play with navigation sensors from multiple vendors using MOSA frameworks for PNT and standard ASPN messaging.

Integrity Monitoring and Notification
Identify and Overcome Potential Threats

NEON PNT algorithms developed by TRX Labs include robust integrity functionality that can accurately detect GPS interference by continuously cross-checking and verifying satellite PNT data against inputs from other satellite sources, inertial sensors, and other available constraints. 

Additionally, TRX Labs has demonstrated the capability to geo-reference and map those threats on a warfighter’s ATAK user interface, while also communicating the threat data to upstream situational awareness platforms.
