What do active GPS systems provide that passive systems do not?

Active GPS systems offer real-time tracking capabilities that passive systems lack. This means that with an active GPS system, the location of an individual can be monitored continuously and instantly. This allows law enforcement and supervising agencies to keep track of an individual's movements as they happen, which is crucial in many probation and parole situations where monitoring compliance with terms of supervision is essential.

In contrast, passive systems typically store location data for later retrieval, meaning they cannot provide immediate location updates. This delay in tracking can hinder timely responses to potential violations of probation or parole terms. The immediate feedback of an active system allows for proactive management and responses to any concerning behaviors or locations, ensuring that public safety interests are upheld.

Audio monitoring, historical tracking, and visual surveillance do not pertain to the core functionality that distinguishes the real-time capabilities of active GPS from the more delayed data collection of passive systems.
