Passive GPS is the least intensive tracking level that we offer as it provides historical tracking data. This historical, next day reporting system uses GPS location latitude/longitude points. All movement points are stored in the TrakMate unit's memory until the program participant returns to his residence and the TrakMate is docked into its docking station, this initiates a memory download into our SenTrak offender tracking database. Detailed reports can be viewed after docking has occurred. All historical data is available 24/7/365.

Our standardized equipment makes it easy to transition a participant to different GPS levels, without requiring additional hardware or software.
