The document discusses a system that uses GPS and GSM technologies to track vehicles and other assets. GPS satellites provide location data that is transmitted via GSM networks. This allows asset owners to monitor locations in real-time through a web application. The system provides security benefits like recovering stolen vehicles and monitoring high-value goods. It could also optimize delivery routes and track animals. Combined GPS and GSM technologies enable low-cost, real-time asset monitoring with potential applications in transportation, security, and logistics.
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.
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.

23. 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.
24. 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.
25. 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.
26. CONCLUSION
The system is about making vehicle more
Secure by the use of GPS, GSM
technology and a web application.
