Vehicle Tracking System using GPS and GSM

This system is a combination of various electronic device, in which we can locate the position of our vehicle by using GPS and GSM technology. Global Positioning Vehicle System (GPS) & GSM is used in Modern Vehicle Tracking System to locate the longitudinal & latitudinal position of vehicle. We can also used other technology to track the vehicle. This technology provide the real time vehicle location. We use microcontroller to control the GPS module to get geographic coordinate position of vehicle. A GPS receiver calculates its position using the signal from GPS satellite. The GPS stored the data from satellite & this data stored in the form of latitude & longitudinal position. To find the path of the vehicle we need to send a message to the GSM, which get activated by receiving our message. At this instant GPS get automatically deactivate by the help of relay & GSM provide the last received position from the GPS and send the message to a particular number which is executed in the program. After this the GSM get deactivate and GPS get activate. This is a cyclic process.
