Zhang Xiangong · Mechanical & Electrical Engineering Technology · 2006
The clock signal provided by Global Positioning System GPS is widely used as a synchronous clock in broadcasting television system and electric power system and the display of time in public. Jupiter 21 GPS Receiver and the information related to time are introduced an ATMega64L microcontroller to process the information and emendate self-punctual time continuously is used and a high precise self-punctual clock is developed and the basic hardware structure and software function are given. The result shows that the apparatus can completely meet the need of application.
