  • Compared with the satellite timing performance under terrestrial stationary condition, it is more susceptible to the effects of visible satellite and space electromagnetic environment under the condition of mobile platform in the far sea and far region. This paper use high-performance cesium atomic clock as the reference external frequency standard for satellite receivers to perform timing tests at test points in the East Siberian sea, the northernmost test point, the Arctic Ocean return point, the Bering Sea test point, and the Japan Sea test point. Based on the number of satellites and frequency accuracy, the dynamic Global Navigation Satellite System (GNSS) multi-system timing performance of distant sea is analyzed. The test results can be used as an important basis for the timing performance evaluation of important waterways in the northern hemisphere and test areas in the polar seas. The test results show that the average number of visible satellites of the GNSS system at all test points is maintained at more than 10, the one-way time difference jitter is maintained within ±20 ns, and the output frequency accuracy can reach the magnitude of 10-13.
