2. CONTENTS INTRODUCTION GPS GSM IMPORTANCE OF GSM IMPORTANCE OF GSP WORKING PRINCIPLE ADVANTAGES FUTURE SCOPE

3. introduction In this urban life transportation is very common. A lot of things occur on the road every day . Therefore the need of security and monitoring is developed. To resolve such problems, a system is developed using GPS and GSM technologies and an application is introduced in this research work.

4. Various problems that we face: 1. In critical condition (when vehicle is stolen), one is confused what to do 2. If one has something expensive and he wants to check it regularly 3. To find the shortest path available

5. . All these problems are overcome by the system. This system has Global Positioning System (GPS) which will receive the coordinates from the satellites among other critical information. Tracking system is very important in modern world. This can be useful in soldier monitoring, tracking of the theft vehicle and various other applications.

6. The system is microcontroller based that consists of a global positioning system (GPS) and global system for mobile communication (GSM). GSM modem, provided with a SIM card uses the same communication process as we are using in regular phone

7. Global positioning system( gps ) The GPS concept is based on time and the known position of specialized satellites. The satellites carry very stable  atomic clocks  that are synchronized with one another and to ground clocks. Any drift from true time maintained on the ground is corrected daily. Likewise, the satellite locations are known with great precision.

8. Cont. GPS satellites continuously transmit their current time and position. A GPS receiver monitors multiple satellites and solves equations to determine the precise position of the receiver and its deviation from true time. At a minimum, four satellites must be in view of the receiver for it to compute four unknown quantities (three position coordinates and clock deviation from satellite time).

10. . Global Positioning Satellites (GPS) enable the tracking of all kinds of mobile assets accurately and provide their real time positions to the owners 24 x 7. GPS provides the latitude/longitude information of the mobile at a given time, this information can be transmitted to any place using the GSM/GPRS radio link.

11. Global system for mobile communication(GSM)

12. . Network structure The network is structured into a number of discrete sections: Base station subsystem – the base stations and their controllers explained Network and Switching Subsystem – the part of the network most similar to a fixed network, sometimes just called the "core network" GPRS Core Network – the optional part which allows packet-based Internet connections Operations support system (OSS) – network maintenance

13. IMPORTANCE OF GSM GSM (Global System for Mobile communications). GSM is a digital cellular communications system. It is used for transmitting mobile voice and data services. International roaming capability. Better security against fraud

14. GSM MODEM GSM modem is used for transmitting and receiving the data. SIM 300 is a tri-band GSM/GPRS engine. It works on various frequencies i.e ; EGSM 900MHZ, DCS 1800MHZ and PCS 1900mhz

15. IMPORTANCE OF GPS GPS (Global Positioning System) GPS always transmits the data GPS Receiver gets the location information from satellites. GPS TRACKING  can be used to track vehicles, equipment, mobile phones, people

16. System architecture It consists of two units : Transmitting side (vehicle unit) Monitoring side .

17. transmission GPS gives information about: 1) Message transmission time 2) Position at that time

18. Monitoring unit The monitoring unit consists of a GSM mobile and a Web Application. The GSM mobile will acquire the position of the vehicle (longitude and longitude) and then by typing those co-ordinates in web application owner of vehicle can get the exact location of the vehicle.

20. WORKING PRINCIPLE The GPS technology uses at least three or four of the 24 satellites for computing the position and location of objects . GPS receivers detect the satellite’s transmitted signals and accurately determine the location. GSM technology determines an object's position by using signal strength and triangulation from base stations . i.e. GSM is used for transmission and receiving data

21. GSM, on the other hand, triangulates the location of a cell phone in a network by using the phone’s international mobile equipment identity, or IMEI, number . GPS  track the location of a device or phone by using digital maps, such as Google maps. …

22. ADVANTAGES Stolen vehicle recovery . Monitors all hazards and threats Alert message to mobile phone for remote information Mobile number can be changed at any time. Location of vehicle or object can be determined anytime.

23. DIS ADVANTAGES The liberty of the person gets restricted. This may lead to business owner to measure the performance of the employee by these stats only and there leaves no room for human analysis. Thus technology carries its whites and blues. It depends on the user how to make it.

24. SCOPE IN FUTURE If anybody steals our car we can easily find our car around the globe and the vehicle can be turned off by only with a simple SMS. To track animals in jungles. Delivery services.

25. CONCLUSION The system is about making vehicle more Secure by the use of GPS, GSM technology and a web application.
