A Global Positioning System tracking unit is a machine that uses the satellite System to determine the particular location of a vehicle, person, or other asset to which it is attach and to record the position of the asset at regular intervals. The recorded location data can be stored within the tracking division, or it may be transmitted to a central location data base, or internet-connected computer, using a cellular (GPRS or SMS), radio, or satellite modem embedded in the unit. This allows the asset's location to be displayed against a map backdrop either in real time or when analyzing the track later, using GPS tracking software.



A GPS tracker is mainly classified into three categories:


• Data loggers
• Data pushers
• Data puller

A GPS logger simply logs the position of the device at regular intervals in its internal memory. Modern 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. In some Private Investigation cases, these data loggers are used to keep track of the vehicle or the fleet vehicle. The reason for using this device is so that a PI will not have to follow the target so closely and always has a backup source of data.


Data pusher is the most common type of GPS tracking unit, used for asset tracking, personal tracking and Vehicle tracking system Also known as a GPS beacon, this kind of device pushes sends the position of the device as well as other information like speed or altitude at regular intervals, to a determined server that can store and instantly analyze the data.



GPS data pullers are also known as GPS transponders. Contrary to data pushers that send the position of the devices at regular intervals, these devices are always-on and can be queried as often as required (pull technology). This technology is not in widespread use, but an example of this kind of device is a computer connected to the Internet and running GPSD.



The most common use of GPS in day to day life is for tracking vehicles. But one should have the permission for this as many of the country don’t allow it to be used public. The best way is to contact with a security service provider as they have the authority to operate a GPS system.
