The FBI Vehicle Tracker

The device actually has two parts, the GPS receiver and the transponder that communicates the data back to its masters at the FBI office.

The Battery

The device draws very little power, and this particular set of batteries packs enough juice to easily last 20 years. Thats a long time to be tracked.

Mounted Under the Car

The battery pack, transmitter and GPS antenna are connected by wires and have their own magnet mounts. They'd be attached in close proximity underneath the car, probably near the edge so the GPS receiver can pick up a signal.

The GPS Board

The circuit board that handles GPS signal processing dates back to 1999 and has a mere 0.125MB of SRAM and 1MB of flash memory. The FBI likely hand-soldered the board by hand, according to iFixit.

The Transmitter

The board contains the ultra-low-power single-chip transceiver. It allows for data transmission and reception. It contains the connections for both the GPS and transmission antennas.

The Teardown: Complete

Remember kids, the FBI can legally track you using one of these. Taken apart, they are just plain circuit boards and batteries.

An Old Model

iFixit took apart a model from several years ago. While there are reports that the FBI is using more modern hardware, they are probably still pretty small. If you or your mechanic didnt stumble over it, you arent likely to notice it.
