Two Piece GPS Systems from iSECUREtrac

iSECUREtrac two piece GPS systems are comprised of two main components: an ankle bracelet or cuff and a Personal Tracking Unit (PTU). The ankle cuff is electronically tethered to the PTU via a radio frequency (RF) signal. If the PTU does not receive an RF signal transmission from the cuff, the PTU records a violation. This violation may indicate that there was an attempt to abscond or circumvent electronic monitoring. Numerous strategies are used by agencies to investigate these violations – including violation resolution by iSECUREtrac's Monitoring Center staff.

 

 

iSECUREtrac two piece GPS systems consistently take, compute and store multiple tracking points every minute, not just when the individual is in a violation status. These stored points are complete with time/date stamps and velocity information. This is extraordinarily useful when the monitored individual is in an automobile and can change location, speed and direction in less than 60 seconds. Systems from other companies may take a single point as infrequently as once every 10 minutes.

The more often the system takes points, the fewer and the smaller the gaps in tracking data. This is particularly true when the offender is in an area with spotty cellular coverage and the system relies upon Assisted GPS. However, it's also true when the offender is traveling through areas where buildings, tunnels, bridges and other obstructions along the route are likely to block GPS satellite signals. The savvy offender may be able to take advantage of systems that track infrequently or those more likely to miss tracks – creating a tracking history that provides far less certainty about offender behavior than systems that record tracks frequently and are less subject to "missing" tracks.

In addition, storing multiple points every minute provides necessary detail on the location and movement of high-risk individuals, including the direction and speed of travel. With more points, it's easier to more accurately discern patterns of travel and travel routes. If there is a deviation from a firmly established pattern, it may warrant further investigation by the supervising officer.
