The usefulness of GSM and GPS has made them popular in their own context; integrating these technologies can prove to be a flamboyant solution for many unsolved problems. The idea of this paper is to integrate these two technologies into one system and provide an effective application for vehicle tracking as well as personal tracking. To implement a multi tracking system use of the following two technologies can be made, firstly GSM(Global System for Mobile) which is a set of standards to describe technologies for Second Generation (2G) and GPS(Global Positioning System) which is a satellite-based navigation system consisting several satellites revolving around the earth. The system will provide solution for tracking and tracing of multiple movable objects at a same time, so the name Multi-Tracking System. We can see the current location of the object and other add-on features, for vehicles there will be live tracing and tracking via GPS, controlling its subsystem parts via GSM network using SMS or GPRS. The whole system will be implemented in Microsoft .Net Technology, for system components C#.net will be used and for web based parts ASP.net will be used.

Consider a transport company having many vehicles, managing all such vehicles keeping a track of their drivers, maintaining all the vehicles is a very hectic job. So there is a need of a system which could maintain all this essential details. We can provide an add-on to this by getting the live location of each vehicle and finding their path, also we can determine what their current speed is. The GPS consists of 3 segments [1] • Space Segment • Control Segment • User Segment The Space Segment consists of a nominal constellation of 24 GPS satellites. Each satellite broadcasts RF ranging codes and a navigation data message. The Control Segment consists of a network of monitoring and control facilities which are used to manage the satellite constellation and update the satellite na- vigation data messages. The User Segment consists of a varie- ty of radio navigation receivers specifically designed to re- ceive, decode, and process the GPS satellite ranging codes and navigation data messages [1]. A GPS receiver calculates its position by precisely timing the signals sent by GPS satellites high above the Earth. Each satellite continually transmits messages that include • The time the message was transmitted • Precise orbital information the general system health and rough orbits of all GPS satellites. The receiver uses the messages it receives to determine the transit time of each message and computes the distance to each satellite. These distances along with the satellites' loca- tions are used with the possible aid of trilateration depending on which algorithm is used, to compute the position of the receiver. This position is then displayed, perhaps with a mov- ing map display or latitude and longitude; elevation informa- tion may be included. Many GPS units show derived informa- tion such as direction and speed, calculated from position changes [2], [3]. GPS tracking systems are used to track anyone and any- thing these days. Technology has rapidly advanced in the past few years and it has become very easy for the average person to use a tracking system. If you have a vehicle, then you may want to place a GPS tracking system under your dash or in your glove compartment. This way, if your car ever gets sto- len, you will be able to locate it within seconds and you can catch the culprit. If you have a small child, you will want to have a tracking system in place in case they get lost or wander off. Every second counts with a lost or abducted child, so a tracking de- vice is imperative to avoid a possible disastrous and heartbreaking outcome. If you have valuable items in your home like jewelry, or electronics you will want a GPS tracking system in case they are ever stolen. There are also various tracking systems that can locate items inside buildings and parking garages. If you have a teenager son or daughter, you will want to use a GPS tracking system to make sure that they are driving responsibly and they are going where they told you they were going. If you suspect your spouse or significant other of cheat- ing, a good tracking system will be able to confirm or absolve your suspicions. T
