Time synchronization apparatus and a method thereof using a global positioning system of a satellite

摘要: A time synchronization apparatus and a method using GPS (Global Positioning System) of satellite. An oscillator oscillates frequency required for Global System counter generates an internal 1 pps by counting the oscillating oscillator. comparator outputs phase difference comparing outputted from signal received System. buffer stores comparison output comparator. first controller corrects counter. second controller. microprocessor synchronizes tracing state signals detected stored in providing correction to outputting error value. digital/analog converter converts value unit into transmits converted operating control adjusting
