GPS and GSM for Accident Spot Identification


The main intention of this project is to find the accident spot at any place and intimating it to

ambulance through the gps and gsm networks. Now-a-days, it became very difficult to know

that an accident occurred and to locate the position where it has happened. It’s very difficult for

the lives of victims until anyone noticed and informed it to the ambulance or to any hospital

and if it occurs in remote areas there will be no hope to survive. To overcome these, gps and

gsm technologies are used. The gps based vehicle accident identification module contains a

The Location Update Message is routed to the HLR through the SS7 network, based on the global title translation of the IMSI that is stored within the SCCP Called Party Address portion of the message. The HLR responds with a message that informs the VLR whether the subscriber should be provided service in the new location.


The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.

GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.
