Embodiment Construction
[0038] In addition to the second pulse output clock, the GPS module in the prior art usually outputs other higher frequency test signals, for example, a test signal with a frequency of 10 kHz, or a test signal whose frequency can be set according to specific needs. The stability of the above-mentioned second pulse signal is better than that of the 10kHz test signal, and the 10kHz test signal has shortcomings such as large signal jitter and poor short-term stability. The synchronous clock is extracted from the GPS clock signal to obtain a stable local clock signal. The present invention overcomes the long-standing bias of using the second pulse signal as the reference clock in the field of satellite clock synchronization, adopts a higher frequency test signal as the reference clock of the GPS clock phase-locked loop, and eliminates the higher frequency by adding corresponding software processing The test signal quality is poor and other shortcomings, so that the local clock sig...
