Active GPS Tracker Detection
Detection and documentation of active GPS tracking devices transmitting real-time location data from vehicles.
GPS tracking devices fall into three operational categories, each requiring different detection approaches.
Active trackers transmit location data in real time via cellular networks. They generate a cellular RF signal detectable by spectrum analyzers when actively transmitting, and require power — either from a battery or from the vehicle's electrical system.
Passive trackers log location data internally with no transmission whatsoever. They are completely invisible to RF detection and must be found through physical inspection and magnetic detection of the device's internal components.
Hardwired trackers draw power from the vehicle's electrical system (OBD port, fuse box, battery terminals) and may be either active or passive. They have no battery to die and can operate indefinitely. They require inspection of wiring runs and power access points in addition to external physical inspection.
Empire Investigation's vehicle GPS sweep covers all three types through a combination of RF scanning, physical inspection of all standard and non-standard concealment areas, magnetic wand scanning along all ferrous body panels, and OBD port inspection.
How Active GPS Trackers Operate
Active GPS trackers use the Global Positioning System to determine location and transmit that data in real time over cellular (3G/4G/LTE) networks to a server or application accessible by the person who placed the device. They are powered by internal batteries or, in hardwired versions, by the vehicle's electrical system. Many devices update location every few seconds and include motion detection to extend battery life.
Where Active Trackers Are Placed
The most common placement locations for magnetic active trackers include wheel wells, the undercarriage near the spare tire, behind bumpers, and inside wheel arches. These locations provide strong magnetic attachment, protection from weather, and concealment from casual observation. Hardwired active trackers are often connected to always-on power sources in the vehicle's engine compartment or interior.
What We Look For
- Magnetic active trackers on the vehicle exterior and undercarriage
- Hardwired active trackers in the engine compartment
- OBD-II active tracking devices in the diagnostic port
- Active trackers concealed in bumpers and wheel arches
- Cellular LTE active trackers with cloud monitoring platforms
