UniTrak is an ankle-worn GPS tracking device. The device is equipped with a 48-channel GPS receiver for highly accurate data point acquisition and location identification. UniTrak sends location data through cellular networks with nationwide coverage.
The tracker offers a host of features that include LED notification lights, vibration messaging, on-board memory, and the latest in tamper alert technology. Sentinel’s patented radio frequency (RF) technology is included, providing at-home communication with corrections agency personnel.
When the participant is home, UniTrak functions as a reliable RF monitoring unit. The device continuously sends participant location to the 24/7/365 National Monitoring Center. This eliminates potential for inaccurate location reporting caused by GPS drift. Advanced Forward Link Trilateration (AFLT) is included as a backup tracking system when GPS signals are diminished or not available.
