Tracking Device Teardown

We partnered with Wired to bring you a peek inside an FBI car-tracking device. The device is similar to the one Yasir Afifi found underneath his car. If you're curious where this one came from, Wired has posted a writeup about Karen Thomas, the woman who found this tracker under her car. They've also posted a video of Kyle doing the teardown.

The device comprises of a GPS unit for receiving the car's position, an RF transmitter for relaying your location to the interested authority (aka the FBI), and a set of sweet D-cell batteries that power the whole enchilada. But we didn't stop there, of course. Read on to find out exactly what components make this secretive device tick.

Step 1 — Tracking Device Teardown
We finally have one of these on the teardown table! Being in its presence, we can almost feel our civil liberties being flushed down the toilet.
Before we whip out the blowtorches and jackhammers, here's a look at the entire tracking system.
Clockwise from the top, the system consists of:
Battery pack
GPS antenna
Transmitter/receiver unit
Magnetic mounting bracket

The components of the system are all attached to the tracked vehicle with extremely powerful magnets. Some were so stubbornly attached that they ripped out of the mounting brackets to forever remain stuck on the undercarriage of the host vehicle.
