In day to day life the man is running behind the technology and accuracy is the going to be major issue for this. In such an accurate world everything should be done on the time management is going to be the major task in this routine life. This project “REAL TIME UNIVERSAL DIGITAL CLOCK IMPLEMENTATION USING GPS” is all about time accuracy. It is designed in such a way that the output displayed on the LCD i.e. the time is going to be very much exact and the display also contains GST time other than local time. The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. The GPS antenna present in the GPS module receives the information from the GPS satellite and it reveals the position information. This information received from the GPS antenna is sent to the controlling station where it is decoded. Thus, the complete data related to the vehicle is available at the controlling unit. The information about the vehicle will be displayed on the graphical LCD continuously since the vehicle is moving and its position coordinates changes continuously.
