Vehicle Tracking System Today vehicles are the common mode of
transportation and traveling, and the demand is increasing day by day. This is a project used to identify the exact position of a vehicle. Here we aim to implement a project to track a vehicle by using the GPS technology irrespective of the purpose they are used.

GPS module The Global Positioning System (GPS) is the only fully functional Global Navigation Satellite System (GNSS) in the world. The United States' Global Positioning System (GPS), which as of 2007 is the only fully functional, fully available global navigation satellite system. It consists of up to 32 medium Earth orbit satellites in six different orbital planes, with the exact number of satellites varying as older satellites are retired and replaced. Operational since 1978 and globally available since 1994, GPS is currently the world's most utilized satellite navigation system. Global Navigation Satellite System (GNSS) is the standard generic term for satellite navigation systems that provide autonomous Geospatial positioning with global coverage. A GNSS allows small electronic
receivers to determine their location (longitude, latitude, and altitude) to within a few meters using time signals transmitted along a line of sight by radio from satellites. Receivers on the ground with a fixed position can also be used to calculate the precise time as a reference for scientific experiments. The GPS uses a constellation of between 24 and 32 Medium Earth Orbit satellites that transmit precise microwave signals, that enable GPS receivers to determine their current location, the time, and their velocity (including direction). GPS was developed by the United States Department of Defense. Its official name is NAVSTAR-GPS. The location information is available as latitude and longitude. It gives the location data from time to time so that when emergency arises we can know where exactly it has occurred.

DISCRIPTION
Vehicle section: In this section the micro controller keeps processing the data from the GPS. The data processed is stored in the micro controller and transmitted via wireless unit to the central monitoring unit. Monitoring Unit: Here a database is created in which the details of vehicle and the list of locations are being listed. Also, there is a list of nearby police stations and hospitals corresponding to the locations. If required the message is send to the vehicle which in turn then sends the location. When a message is received from a vehicle, the location send by it is analyzed and its corresponding police station and hospital numbers are found out. After that messages are being send to the former ad latter with the location.
