Abstract

A closed-loop physical high accuracy time synchronization method for the future orbit-application of satellite is proposed. Differences and advantages of the proposed system are compared with other time synchronization methods. The basic time synchronization model and error propagation model for remote systems are built. Based on the two-way range measurement and time transfer technology, the principle for obtaining high accuracy clock bias is analyzed. The dependence between time and frequency domain parameters for clock adjustment loop is given. A high accuracy time synchronization system for ground experiment is constructed. The clock bias measurement precision under open-loop non-clock adjustment status, time synchronization accuracy under closed-loop clock adjustment status, and long term time synchronization monitoring results are given. The experiment results show that the accuracy of proposed time synchronization method is superior to 1 ns, providing a new method for studying high accuracy time synchronization.
