The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location data base, or internet-connected computer, using a cellular, radio or satellite modem embedded in the unit.” according to wiki.

Data Loggers:
A GPS logger is a GPS tracking system that simply logs the position of the device at regular intervals in its internal memory. GPS loggers have either a memory card slot, or internal flash memory and a USB port. Some act as a USB flash drive. This allows downloading of the track log data for further analyzing in a computer.
Data pusher:A GPS receiver and a mobile phone sit side-by-side in the same box, powered by the same battery. At regular intervals, the phone sends a text message via SMS, containing the data from the GPS receiver.
Data pullers : Contrary to a data pusher that sends the position of the device at regular intervals push technology, these GPS tracking devices are always-on and can be queried as often as required. Data Pullers are coming into more common usage in the form of devices containing a GPS receiver and a cell phone which, when sent a special SMS message reply to the message.
GPS tracking systems are now commonly used in all industries.
