AI Technical Summary
In existing technologies, single-station time synchronization methods suffer from significant errors in time synchronization results when faced with complex spatial environments and human interference, making it difficult to guarantee the accuracy and stability of time synchronization.
A multi-station time synchronization joint verification method is adopted. By collecting satellite observation data from two time synchronization stations to be verified, the inter-station differential observation equation and the single-difference station satellite distance equation are constructed. The relative coordinate parameters of the rover station are calculated and compared with the reference values to verify the reliability of the time synchronization station.
It improves the accuracy and stability of time synchronization results, effectively avoids the influence of external interference signals, and ensures the reliability of time synchronization.
