Thread: cheap anti theft GPS trackers?

GPS is basically a set of satellites that operate a very accurate clock. when your receiver receives signal it locates you by the time differential between the satellites
but..........to transmit that info remotely back to you is where it gets into the $
i fitted a $80 aliexpress special into a car and it worked fine, cost $20 for the prepay sim and didnt access it till i needed too. worked well
it was connected to the vehicles battery, drew bugga all current and had a 14 day standby if the battery was connected.
but of course it depended on a local cell service so no service no tracing, so take it into a bad signal area or chuck the vehicle into a shipping container and say goodbye.
