TRX Systems is a small high-technology Maryland company whose primary focus is to combine advances in miniature electronic sensors and innovative signal processing techniques to yield low-cost/high performance personally-worn location-aware devices.
Focus on First Responders
TRX Systems is currently developing the Firefighter Sentinel System , a technological breakthrough in the field of tracking first responders both outdoors and within complex structures.

“More than 1000 firefighters have died in the line of duty over the past decade. One of the leading causes of firefighter death and injury is the inability of rescuers to locate and extract firefighters trapped in a structure or overcome by the progress of the fire.” -PWSN Report
Recognizing the urgent need to mitigate this inadequacy, TRX Systems, driven by its innovative team of engineers and backed by years of research experience, has prototyped their Firefighter Sentinel System with tracking results unparalleled by existing methodologies. The Firefighter Sentinel System is comprised of mobile units smaller than the size of a cell phone worn by each firefighter at the incident scene. The mobile units form a network controlled by a Base Station unit connected to a rugged laptop which displays each firefighter's location and vital sensor information (heart rate, temperature, etc.) on TRX Systems' Graphical User Interface. The Firefigher Sentinel System provides the incident commander with crucial information regarding each firefighters situational and positional information, providing a vital tool for decision making, targeted at saving lives.

The Firefigher Sentinel System is supported by the Department of Homeland Security (DHS), and the Maryland Fire and Rescue Institute (MFRI) promises to be the first self-contained system that tracks first responders both indoors and outdoors with the required precision.
Our system offers:
- A highly accurate, rapidly deployable, personnel locating system
- Pager sized mobile units requiring no on-site calibration and a minimum system set up time
- Graphical User Interface at the incident command center to provide a tool for crucial life saving decisions to be made on the basis of facts
