  • Traditional time synchronization method could reach a high precision for distributed nodes, but does not apply to the spatially non-contact nodes. In order to solve the above problems, a time synchronization method based on pseudorange differential GPS was proposed, and the system principle and synchronization scheme are given. Moreover, the clock model of the Anchor Nodes (ANs) is built to estimate synchronization parameter, which is solved by the Total Least Squares (TLS) method. The Kalman Filter (KF) method is derived from the theoretical time synchronization module, which can enhance the real timing and precision. The results of numerical simulating show that the proposed system synchronization and parameter estimation methods can control the synchronization accuracy of distributed node in sub-nanosecond level.
