Interfacing GPS with 8051 Microcontroller

Applications:

• The proposed system can be used in marine navigation, car navigation and fleet management
• Can be used for tracking and mapping applications
• Can be used for custom navigation and positioning
• Can be used for finding the location of any user

Project Implementation:

• LCD data pins should be connected to the port2 of the controller and the control pins RS, RW and EN are connected to the P1.0, P1.1 & P1.2 respectively
• The LCD is used for displaying the latitude and longitude values of the location
• The receiver pin of the GPS module is connected to the 13th pin of max232 IC and Gnd pin to the ground
• The controller RXD pin is connected to the 12th pin of max232 IC
• The GPS module transmits the data continuously as per the NMEA standards using the RS232 protocol. For this the latitude and longitude values of location will be available in GPRMC sentence.
• The values of project latitude and longitude are extracted from NMEA format and will be used to display on LCD
• The data from the GPS module will be received serially using UART protocol and the latitude and longitude values received will be displayed on LCD

Project Description:

• The program should be burned into the 8051 microcontroller
• The connections for the project should be provided as per the circuit diagram
• The power supply for the GPS module can be given using a DC power adapter
• Then, interface the GPS module to the computer and open hyper terminal to check the received messages
• Then the GPS module will get activated
• The GPS module should be then connected to the circuit and the values of the longitude and latitude will start displaying on the LCD
