Introduction- In Vehicle tracking project, you can track the

location of your Vehicle. This project gives about vehicle location by

sending sms through GSM modem. This SMS contains longitude and latitude of the

location of vehicle.  Microcontroller is the central processing unit

CPU of our project. Microcontroller gets the coordinates from GPS

modem and then it sends this information to the user in Text SMS.

What is Vehicle Tracking & locking System?

The device consists of a micro-controller interfaced with a GPS and a GSM module

The GPS module receives the information of the vehicle and passes it to the controller.

The controller extracts the required information and makes a packet out of it that consists of geographical data and other information.

This packet is passed to the gsm device that is configured for point to point

A software will display the current position of the vehicle on the map

By the gsm module we can lock the fuel of vehicle when we want to do this.

GSM Module

GSM module is used to establish communication between a computer and a GSM system. Global System for Mobile communication (GSM) is an architecture used for mobile communication in most of the countries. Global Packet Radio Service (GPRS) is an extension of GSM that enables higher data transmission rate. GSM/GPRS module consists of a GSM/GPRS modem assembled together with power supply circuit and communication interfaces (like RS-232, USB, etc) for computer. The MODEM is the soul of such modules.

GSM MODEM

GSM MODEM is a class of wireless MODEM devices that are designed for communication of a computer with the GSM network. It requires a SIM (Subscriber Identity Module) card just like mobile phones to activate communication with the network. Also they have IMEI (International Mobile Equipment Identity) number similar to mobile phones for their identification. A GSM/GPRS MODEM can perform the following operations: 1.      Receive, send or delete SMS messages in a SIM.2.      Read, add, search phonebook entries of the SIM.3.      Make, Receive, or reject a voice call. The MODEM needs AT commands, for interacting with processor or controller, which are communicated through serial communication. These commands are sent by the controller/processor. The MODEM sends back a result after it receives a command. Different AT commands supported by the MODEM can be sent by the processor/controller/computer to interact with the GSM cellular network.

How GPS WorksThe GPS system currently has 31 active satellites in orbits inclined 55 degrees to the equator. The satellites orbit about 20,000km from the earth's surface and make two orbits per day. The orbits are designed so that there are always 6 satellites in view, from most places on the earth.The GPS receiver gets a signal from each GPS satellite. The satellites transmit the exact time the signals are sent. By subtracting the time the signal was transmitted from the time it was received, the GPS can tell how far it is from each satellite. The GPS receiver also knows the exact position in the sky of the satellites, at the moment they sent their signals. So given the travel time of the GPS signals from three satellites and their exact position in the sky, the GPS receiver can determine your position in three dimensions - east, north and altitude.There is a complication. To calculate the time the GPS signals took to arrive, the GPS receiver needs to know the time very accurately. The GPS satellites have atomic clocks that keep very precise time, but it's not feasible to equip a GPS receiver with an atomic clock. However, if the GPS receiver uses the signal from a fourth satellite it can solve an equation that lets it determine the exact time, without needing an atomic clock.

Block Diagram of GPS module-

If the GPS receiver is only able to get signals from 3 satellites, you can still get your position, but it will be less accurate. As we noted above, the GPS receiver needs 4 satellites to work out your position in 3-dimensions. If only 3 satellites are available, the GPS receiver can get an approximate position by making the assumption that you are at mean sea level. If you really are at mean sea level, the position will be reasonably accurate. However if you are in the mountains, the 2-D fix could be hundreds of metres off.A modern GPS receiver will typically track all of the available satellites simultaneously, but only a selection of them will be used to calculate your position.

Longitude = 18 38.6878 N Latitude = 73 45.3423 E

How to track the location on Actual Map

It would be time consuming to track location on Printed maps. But now a days various websites are available on internet which shows online map.

Google maps is one of the main and useful website to track or find the location of vehicle.

You can track the location using Longitude and Latitude received in SMS.

Using these maps you can get the exact location as well as directions to go to those places from your current/desired location.

Actual picture of project -

Applications-  School transport Tracking: “Vehicle

tracking system” can be used in the school bus for tracking.

This project can be used for detection of cab or car of companies.

Theft Protection: This project can be very useful when your vehicle or car is stolen.

Sectors in which VTS is used Logistics, Cargo, Distribution, TransportationFleet management

Public ServiceVTS avoids misusage

RailroadsVTS can monitor the wagons online

Private Yatches and Fishing Boats VTS locates the vehicle in case of emergency

School and EmploymentVTS can alert when vehicle is approaching

Working VehicleMonitoring vehicle which project they are working

PoliceCommunication with other vehicles

Rent a Car FirmsMonitor the vegicle in agreement terms

Future development-  We can monitor some parameters of

vehicle like overheat or LPG gas leakage

We can dial an emergency call if the vehicle goes out of a certain / pre-decided track.

This system can also be used to send information to the predefined mobile no. in case of accident .
