Wireless Clock Synchronization System Based on Long-wave Signal Sensing

The clock synchronization error between nodes affects the positioning accuracy of the navigation system and the performance of the Time Division Multiple Access(TDMA) system. Aiming at the special case of satellite timing failure, a wireless clock synchronization system based on long-wave signal sensing is proposed. By estimating the radio frequency parameters of the non-cooperative long-wave signal, the system calculates the clock deviation between the reference station and the receiver and completes the clock synchronization between them. The simulation results show that the system using this technology can achieve sub-microsecond accuracy in clock synchronization, and has high application value.
