Abstract

Abstract

In order to solve the problems of time synchronization accuracy degradation of two-way time transfer due to relative motion between nodes in Flying Ad hoc NETwork (FANET), a full-duplex Two-Way Time Transfer (TWTT) method is proposed. Firstly, a system of equations to be solved is constructed according to the full-duplex two-way time transfer procedure, and the synchronization error expression for single full-duplex two-way time transfer is derived. Then, the convergence of iteratively performing full-duplex two-way time transfer with or without frequency offset is analyzed. Finally, the performance of full-duplex two-way time transfer method is compared with traditional two-way time transfer methods by simulation analysis and experimental validation. The simulation and experimental results show that full-duplex two-way time transfer method can achieve the same time synchronization accuracy as the physical layer timestamps under high-speed maneuvering between nodes, and the synchronization accuracy is better than the existing motion compensation methods.
