Subterranean Mapping and Tracking of Dismount Personnel: Operational Field Test and Demonstration
Carole Teolis, and Jeff Kunst, TRX Systems
Location: Beacon A (Floor 4)
Date/Time: Tuesday, Jul. 10, 4:45 p.m.
Real-time subterranean mapping and dismount personnel tracking represent the most challenging GPS-denied applications. During late 2017 and early 2018, TRX performed capability benchmarking and demonstrations at three sites: Guardian Center, GA, San Diego, CA, and Muscatatuck Urban Training Center, Indiana (March 2018). During this operational system demonstration, TRX will show real-time logs taken in subterranean environments, focusing on a) man-made environments, b) urban environments - both mapped and unmapped.
The TRX solution being demonstrated is the TRX NEON GPS-denied location and mapping system. This system consists of a small wearable tracking accessory (accelerometer, compass, gyroscope, pressure, and UWB ranging sensors) which pairs with an end user device. The End User Device runs navigation constraint algorithms that fuse the inertial path generated by the tracking unit with available GPS, dropped beacon locations, person to person location constraints (sharing constraints from external position/location systems) and any available map data. An API allows use of the GPS-denied location information by third party applications, including ATAK (where a production plug-in is available) and the Blueforce Development application (integration with which was demonstrated in San Diego).
