Introduction
Vehicle tracking by GPS -
 Vehicle Tracking System (VTS) is the technology used to determine
the exact location of any vehicle using different methods like GPS
and other radio navigation systems operating through satellites
and ground based stations. This device is used to determine the
precise location of a vehicle, and intimate the position to the
concerned authority through an SMS.
 This system is an important tool for tracking each vehicle at a given
period of time and now it is becoming increasingly popular for
people having expensive cars and hence as a theft prevention and
retrieval device.

GSM

Max232
 Max232 is designed by Maxim
Integrated Products.
 It is a dual transmitter / dual receiver
that typically used to convert the RX, TX,
CTS, RTS signals.
 It has two receivers that convert from
RS-232 to TTL voltage levels
 And two drivers that convert from TTL
logic to RS-232 voltage levels.
GSM

GSM
 GSM is Global System for Mobile Communication.
 It is one of the leading digital cellular system.
 GSM is a standard set developed by the European
Telecommunications Standards Institute (ETSI).
 GSM modem is used for transmitting and receiving the data.
GSM

GSM
 SIM 300 is a tri- band GSM/GPRS engine.
 It works on various frequencies i.e. EGSM 900MHz, DCS
1800MHz and PCS 1900MHz.
 GSM Modules can be communicated to PIC-Microcontroller
using normal serial USART protocol.
GSM

Resistor
s
 Resistor limits the electrical current that flows
through a circuit.
 Resistance is the restriction of current.
 The energy of the electrons that pass through the
resistor are changed to heat and/or light.
 These are used to reduce current flow, adjust
signal levels and to divide voltages.
GSM

Capacitors
 Capacitor is a electrical component that
stores electrical energy in an electric field.
 Most capacitors contain at least two electrical
conductors in the form of metallic separated
by a dielectric medium.
 Capacitors are widely used in electronic
circuits for blocking direct current while
allowing alternating current to pass.
GSM

Voltage Regulator
 Voltage regulator is designed to
automatically maintain a constant voltage
level.
 It may be a simple "feed-forward" design or
may include negative feedback control
loops.
 Depending on the design, it may be used to
regulate one or more AC or DC voltages.
GSM

Global Positioning System (GPS)
 GPS is a satellite navigation system that furnishes location and
time information in all climatic conditions to the user.
 It is used for navigation in planes, ships, cars and trucks also.
 The system gives critical abilities to military and civilian users
around the globe.
 GPS module with 9600 baud rate is used to receive the data
from the satellites.
GSM

Features of GPS
 24 Satellites at different orbits.
 Revolve around Earth twice a day.
 For a 2D location, 3 GPS Satellites are used.
 For a 3D location, more than 3 Satellites are used.
GSM

Liquid Crystal Display (LCD)
 Liquid crystal display (LCD) is a flat panel display or video
display that uses the light modulating properties of liquid
crystals.
 LCDs are used in a wide range of applications
• Computer monitors.
• Instrument panels
• Aircraft cockpit displays.
• Television.
GSM

Liquid Crystal
Display
 These are energy efficient and offer safer disposal.
 Its low electrical power consumption enables it to be
used in battery.
GSM

Circuit Description
 Vehicle tracking by GPS - GSM consists of a microcontroller, GPS
module, GSM modem and 9V DC power supply.
 GPS module gets the location information from satellites in the
form of latitude and longitude.
 The microcontroller processes this information and sends it to
the GSM modem.
 The GSM modem then sends the information to the owner’s
mobile phone.
GSM

Working Principle
 Vehicle Tracking by GPS – GPS consists of GPS receiver and GSM modem
with a micro controller.
 The whole system is attached to the vehicle.
 One GSM mobile phone is attached to the computer with VB(Visual
basic) application.
 So the GPS system will send the longitudinal and altitude values
corresponding to the position of vehicle to GSM Modem.
GSM

Working Principle
 Imagine the bus has left from Hyderabad at 8 o clock in the
morning.
 If the officer in charge for that vehicle wants to know where the
vehicle is, he will come to the computer and click on the vehicle
number on the VB program.
 The VB program will send an SMS to the vehicle number.
 The SMS sent would come through the GSM service provider and
then reach the vehicle, which is traveling.
GSM

Working Principle
 Because the vehicle has a GSM device with SIM card.
 This GSM modem will receive the SMS and send to the microcontroller
in the vehicle.
 The microcontroller will receive this SMS and compare the password
and the command.
 If every thing matches then it will perform the request required by the
office.
GSM

Working Principle
 Name of the place is assigned for each longitude & latitude.
 The GSM receiver in the vehicle office receives these data &
gives to the PC through serial port.
 The VB program in the PC checks this data with its database
& displays the details of the vehicle on the screen.
 The device is password controlled i.e. person who knows the
device password only able to operate.
GSM

Working Principle
 In case of any mishaps such as fire , theft or obstacle ,the device will
automatically send an alert to the registered number i.e, the number
that is feeded into the memory of microcontroller.
GSM

Testing
 Connect the circuit to GPS and GSM modem.
 Switch on the circuit.
 Switch on the GPS module and wait for 10-15 minutes for initialisation.
 Switch on the GSM modem.
 Dial the mobile number in the GSM modem. After two rings, the
ringing stops automatically.
GSM

Testing
 Wait for a few seconds. You will get an SMS alert in your mobile.
 Check your SMS inbox. You will see the latitude and longitude data
in the form of SMS text.
 Open a standard map and locate the point on the map.
 You can also enter latitude and longitude values in a software
on any suitable software.
GSM

Applications
 Stolen vehicle recovery.
 Field service management.
 It is used for food delivery and car rental
companies.
 Easily installed in any vehicle such as cars, boats
and motorbikes.
 It can be used to track animals in the jungle.
GSM

Advantages
 It provides more security.
 We can access the system from the remote place.
 It reduce vehicle abuse.
 Fleet monitoring.
 Route monitoring.
GSM

Limitations
 If there is noise in edge detected image, then it is
hard to track the vehicle.
GSM

Conclusion
 Vehicle Tracking System using GPS and GSM all about
controlling theft of a vehicle and to find out the exact location
of any vehicle. The system is about making vehicle more
secure by the use of GPS, GSM technology and a web
application. Vehicle Tracking system resulted in improving
overall productivity with better fleet management. Vehicle
tracking both on case of personnel as well as business purpose
improves safety and security.
