AbstractThe accuracy of TDOA estimation between sites affects the final positioning calculating the performance of the target. The problem needs to be solved in the multi-station localization systems, requires highly accurate phase synchronization for consistency errors cancellation of receivers. In this paper, the impact of phase error on TDOA localization is analyzed briefly, and we proposed a TDOA multi-station positioning system based on a phase synchronization technique via a long round-trip FOL. By comparing with an actual GPS timing TDOA based method, we demonstrated that the performance of the proposed technique can approximately triple the positioning precision. The simulation results show that the FOL synchronization technique can be used as a potential synchronization method of TDOA multilateation system due to its effective phase error cancellation.
