The Short Answer
So GPS is a completely passive technology. A GPS receiver listens to signals broadcast by a group of satellites at known locations, and uses the timing difference between those signals to calculate its own location relative to the satellites. But the end result is that *only the GPS receiver knows its location*. The satellites don't even know that it exists. But if you want to track someone remotely, how do you get the location off of the GPS receiver and onto your computer/phone screen? You have to have it transmit its location somehow. For instance, over the cellular phone network. And *that* is what you're paying for. Without a subscription, the tracker will still know where it is; that costs nothing. But it won't be able to remotely *tell* you where it is.
