Under static conditions; at present; mature technologies for long-distance and high-precision time synchronisation include satellite common view (CV) and two-way satellite time and frequency transfer (TWSTFT) and so on. However; under dynamic conditions; research on high-precision time synchronisation technology is relatively lacking such as mobile platforms on the sea. Considering the dynamic conditions of mobile platforms on the sea; a method of position's smooth filtering with velocity is proposed to improve the accuracy of position measurement; reducing the time measurement error introduced by position error. The proposed method ultimately improves the CV comparison accuracy between sea surface mobile platforms. The simulation and actual test results show that by using the method of position's smooth filtering with velocity; the CV comparison accuracy between mobile platforms on the sea can reach 10 ns.
