Design and Implementation of a High-precision Wireless Clock Synchronization System Based on UWB

The performance of wireless distributed systems is largely determined by the accuracy of clock synchronization. However, most of the current high-precision clock synchronization solutions rely on GNSS or other auxiliary sources to complete. In this paper, a multi-agent cooperative wireless high-precision clock synchronization solution based on Ultra-Wide Band (UWB) is proposed. Through the measurement and calculation of the distance and delay between nodes, and the multi-agent consistency theory, high-precision wireless network clock synchronization is realized. The designed solution is verified based on the hardware-in-the-loop verification system. Experimental results show that the method can achieve clock synchronization better than 1ns.
