WHAT IS GPS? GLOBAL POSITIONING SYSTEM
A network of satellites that continuously transmit coded information , which makes it possible to precisely identify locations on earth by measuring distance from satellites.
By having received the almanac and ephemeris data , the GPS receiver knows the position (location) of the satellites at all times

WHAT IS GPRS? GENERAL PACKET RADIO SERVICE
It is a mode in which resources are assigned to user only when data needs to be sent or received.
Data is sent in packets , which are routed across the network along with other user traffic.
GPRS provides the transmission of IP packets over existing cellular networks.

WHAT IS VEHICLE TRACKING SYSTEM? “Vehicle Tracking Service “ means an Electronics device that reports its location by using Global Positioning system (GPS), data receive from GPS satellites.
This device is installed in car/vehicle with antenna and tracking the vehicle.GPS controlled and handled by computer system.
Thus there is a continuous track of the vehicle which can be stored in a database and can be retrieved later.

The device consists of a micro-controller interfaced with a GPS and a GPRS 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 BRIEF DESCRIPTION OF PROJECT |

DISCRIPTION CONTINUE… This packet is passed to the GPRS device that is configured for point to point service.
The remote receiver consists of a GPRS module interfaced with pc.
A software will display the current position of the vehicle on the map. |

NMEA PROTOCOL GPS module follows NMEA protocol to interface with microcontroller.
It helps to send different frames received from the satellites.
These frames contains parameters of vehicle like longitude, latitude , date , time , speed etc. |

NMEA0183 PROTOCOL National Marine Electronics Association 0183 (NMEA-0183)
(Inter)National standard for navigation data exchange among marine electronics (GPS, LORAN, wind/water speed sensors, autopilot, etc)
Adopted by GPS community as defacto standard for simple output-only Position-Velocity-Time reporting
Available on nearly every commercial GPS with a serial port
Uses standard serial port (RS-232C) at 4800,8,N,1 default
Output-only ASCII-only comma-delimited string-based protocol
NMEA strings:
$GPGGA – GPS fix data message (lat, lon, time, #SVs, etc)
$GPGGL – Geographic position (lat, lon, time)
$GPGSA – GPS DOP and active satellites (SVs, P,H,VDOP)
$GPGSV – GPS satellites in view (SV elevation/azimuth, SNR, etc)
$GPVTG – GPS velocity and heading
$GPZDA – Time & Date message |

AT COMMANDS FOR GPRS AT commands is use for GPRS module to pass the information from in -vehicle unit to base station GPRS module
There are many types of AT commands:
1. GPRS COMMAMND
2. SIM TOOLKIT COMMAMND
3. DATA COMMANDS
4. SMS COMMANND |

UNIQUE FEATURES OF PROJECT If a vehicle is outside the range of the GPRS service ,it is possible that a remote device may not able to know the position of vehicle in that time gap.
For that purpose there is MMC card which stores the data even when the vehicle is out of range and this data can be retrieved later.
The locking of a vehicle from the remote pc.
