摘要：The clock system (100) corrects the instant time using a signal transmitted froma stationary satellite (10). In the clock system, a high-frequency-signal transmitted fromthe stationary satellite is converted to an intermediate-frequency-signal by an analogue-signal-processing-circuit (12), then converted into a digital signal, and finally decoded to adigital signal by a digital-signal-processing-circuit (14). A CPU (15) of the systemcalculates the stationary-satellite-time out of time data included in the signal

transmitted, further the CPU converts it to a co-ordinated universal time (UTC). The clocksystem corrects the time of a clock circuit (18) with the UTC and displays it on a display(19). As a result, a user of the system at a fixed point on Earth can always receive the timedata from the same satellite, so that the clock system can keep time with high accuracy.
