A fully functional and efficient GPS System involves and is dependent on multiple factors such as GPS Receivers  , Satellites , Data Carrier (GPRS) , Data Processing Server , End User

The above image illustrates the basic working of a GPS system
GPS system is used to track the movement of something like a vehicle or even human beings but in actual we are tracking the movement of GPS Device which is fitted / carried by the vehicle or humans .

 Each GPS device has an inbuilt GPS receiver which is connected with GPS Satellite through which device gets the GPS coordinates of the location .

The device also have a GSM module through which device can communicates over GPRS , this GPRS is the communication medium by means of which device sends the data to the Data servers  for storage and further processing of Data. 

These servers also runs a GPS tracking Application through which we can track the actual movement of the devices over map and in reports.
