UniTrak is an ankle-worn GPS tracking device that comes complete with a tamper-resistant fiber optic hypoallergenic strap. Equipped with a 48-channel GPS receiver for improved point acquisition and precise location identification, UniTrak communicates over cellular networks that offer dependable nationwide coverage.
UniTrak comes standard with a host of features that include LED notification lights, vibrating motor, onboard memory, and the latest in tamper alert technology. It also includes Sentinel’s patented built-in redundant radio frequency (RF) technology for enhanced tracking while the participant is at home.
When the participant is home, UniTrak functions as a reliable RF monitoring unit that continuously communicates the participant’s location to Sentinel’s 24/7/365 National Monitoring Center via a Sentinel home monitoring unit. This eliminates the potential for GPS drift when the participant is home.
When utilizing an HMU with UniTrak, drift point s are eliminated without the use of home zones. Further, if the GPS reception is less than optimal, UniTrak devices are equipped with Advanced Forward Link Trilateration (AFLT) as a secondary tracking system.
