In addition to providing directions, GPS technology can be used
for surveillance and safety. The most basic GPS tracking systems
allow users to follow the location of a person, car, pet, or
anything that moves or is moved.
The major components of a GPS tracking system include the actual
tracker and the receiver. The receiver is usually plugged into a
computer's USB port, and then the history of the tracker's movement
can be reviewed. GPS trackers are very affordable and they are
similar in size to USB flash drives.
