There are basically two types of vehicle tracking devices. These include active and passive. Passive devices are known for the storage of GPS location, heading and speed. The device is removed from the vehicle and the data is transferred to the server. There are passive devices which transfer data with the help of wireless media. The only difference between passive and active devices is that active devices transmit the data via modem, or satellite network to a centralized system. The public transport use both of these tracking systems where in the data is transmitted to the server whenever the network is available and when there is an interruption then the data is stored in the memory for later retrieval.

There are three steps that the GPS tracker is responsible for. Firstly it receives the data, stores the data and then transmits the data on demand. There is a User Interface which can be used to access this information.
