There is no such thing as a "GPS Tracker" other than some lame moniker some lame maker slapped onto one of their systems, which others then adopted. A system that USES a GPS receiver. There are transmitting trackers, which USE a GPS receiver to gain a position resolution. Tying them together by naming the entire system using the receiver name as a key identifier doesn't change the facts. They are separate systems.

The fact is that at best, the damned things are nothing more than a trip log, even if they transmit their poll results to a remote storage location.

It too has not a goddamned thing to do with GPS. Lo Jack is ONLY a radio locator beacon, and nothing more. It sends OUT pings and that is what the cops find. There is no data transmitted at all. The pings only consist of a carrier and unique ID pulsing. The Lo Jack Transmitter gets turned on when a satellite or ground based transmitter sends out commands to turn on a specific Lo Jack device. The one that is in the car that just got reported stolen. All the other Lo Jacks do not turn on because they are initialized by the transmitter in a unique ID manner. Lo Jack on a laptop simply works by reporting the laptop's assigned IP address to the Lo Jack security servers. They then locate that IP address' 'subscribed' 'owner', and execute a search warrant on that person, or resolve who the culprit is until they finally get him.
