High-precision timing system and method with navigation satellite adopted

The invention relates to a high-precision timing system and method with a navigation satellite adopted. The method includes the steps that firstly, whether the timing system is successfully positioned or not is confirmed; secondly, whether a PPS signal provided by a satellite signal receiving module is continuously effective or not is judged; thirdly, timing is carried out through the satellite PPS signal; fourthly, punctuality is carried out through a local clock signal. According to the high-precision timing system and method with the navigation satellite adopted, a constant-temperature crystal oscillator is disciplined through the PPS signal provided by the navigation satellite, and control parameter changes are recorded in the disciplining process; under the punctuality state, the frequency of the local clock signal is compensated for and adjusted according to changing conditions of the control parameters under the timing state. After the timing system loses a navigation satellite reference signal, synchronization between the timing system and the satellite can still be kept according to a PPS reference signal obtained through local clock signal frequency demultiplication, the punctuality ability of the system is greatly improved, and long-time punctuality work can be more precisely completed.
