The GPS receiver is used to get accurate geographical location by receiving information from satellites. It receives information from satellites and gives location information in terms of latitude and longitude. It gives latitude and longitudes with accuracy of degree-minute-second. Using this latitude and longitude co-ordinates one can easily trace out the location on entire globe. The GPS receivers have enormous applications.The GPS receiver gives output serially in form of strings with NMEA 0183 protocol. These strings are received serially by host computer or host processor/controller for display or to take any decision or action. The following figure shows the output of GPS receiver on hyper terminal of desktop computer.

In present times increasing Traffic is adding to the big woes of developing cities. The main roads are packed with vehicular traffic on each and every road or a traffic signal (Intersection Points). One comes across the common problem of traffic jams on almost all Traffic Junctions which is even critical if you go to big cities. A lot of time, energies besides precious fuel is wasted just because of these Traffic Jams on the roads.To solve this problem Traffic Cameras are used over Traffic Intersection points. Traffic Cameras capture the image of vehicles in traffic and sends to MATLAB. Here in this project Traffic Surveillance System is demonstrated by way of how the traffic could be controlled over traffic intersection points from the Traffic Control Room. This is a very effective system for Traffic Surveillance.

This system is not only efficient, but also worthy to be implemented. The Accident Detection and Messaging System can be fitted in the vehicle (Ambulance or the Police) and they are duly informed about any such untoward incident immediately.  

This circuit is designed for tracking the location of vehicles. Most oftracking systems are made by using GPS. This is very simple and cheap. Tracking systems are mostly used by fleet operators for tracking a vehicle location, routing and others. This is a very good method for preventing our vehicles from stolen. This tracking system sends us the geographical coordinates and by using these coordinates we can track our vehicle position on electronic maps using internet. By using these tacking systems we can share real time information about transportations. And also can be share real time information or position of trains and buses with passengers. Means passengers can see the real time of arriving busses or trains at the platforms on LCD or on Mobiles.  

The AVR microcontroller boards which are provided with all the basic circuitry for the operation of the microcontroller which has been flashed with the Arduino boot-loader are called Arduino boards. The Arduino board has all the required circuitary to get the built-in AVR microcontroller running. When it comes to programming the Arduino board anyone who have basic knowledge of c programming can quickly get started with the Arduino IDE. Hence the Arduino forms an easy prototyping platform for both beginners and experts.A microcontroller can communicate with the user by several means including LED display, sound generation, using the serial communication etc. The most commonly found output device in a microcontroller board is an LCD display module.  

Every single location in the entire globe can be specified in terms of geographical coordinates. The geographical coordinate is a system which specifies any given location on the earth surface as latitude and longitude. There are devices which can read the geographical coordinates of a place with the help of the signals received from a number of satellites orbiting the earth. The system of satellites which helps in the positioning of a place is called Global Positioning System (GPS). The devices which can read the geographical coordinates of a place with the help of at least four GPS satellites are called GPS Receiver or simply GPS module.The GPS module continuously produces a set of data regarding the position of the earth surface where it is situated which includes the current position with respect to the equator of the earth in terms of Latitude and Longitude. 

 Global Positioning System is based on satellite navigation technology. A GPS Receiver provides the accurate location of an object in terms of latitude and [[wysiwyg_imageupload::]]longitude. Accurate time calculation with respect to GMT can also be done by using GPS. For more information on different data obtained through GPS, refer GPS Receivers. Here a PIC microcontroller has been interfaced with a GPS module to extract its position information (location).  The main objective here is to find the location of the GPS Receiver in terms of latitude and longitude. The GPS module gives output data in RS232 logic level format. To convert the RS232 logic level into TTL, a line converter MAX232 has been connected between GPS module and PIC18F4550. (Also refer PIC USART) The circuit connection of GPS module with microcontroller is shown in the circuit diagram tab. The latitude and longitude data has been displayed on a 16×2 LCD interfaced to PIC.

The data obtained from GPS receiver (GPGGA sentence) is processed by the microcontroller to extract its latitude and longitude values.The GPS Module has been interfaced with AT89C51 and the location values are displayed on a 16×2 LCD interface. The GPS module continuously transmits serial data (RS232 protocol) in the form of sentences according to NMEA standards. The latitude and longitude values of the location are contained in the GPGGA sentence (refer NMEA format). In this program, these values are extracted from the GPGGA sentence and are displayed on LCD.The serial data is taken from the GPS module through MAX232 into the SBUF register of 8051 controller (refer serial interfacing with 8051). The serial data from the GPS receiver is taken by using the Serial Interrupt of the controller.
