| Abstract: | The Space Tracking Ship is an important part of China’s space TT&C network. Its comprehensive TT&C capability is strong.It can not only make up for the shortage of limited land area,but also provide emergency TT&C support for domestic and foreign land stations. It has gradually become an indispensable part of China’s satellite TT&C system. In order to ensure the successful completion of the maritime TT&C task,the accurate navigation and positioning is an important basic guarantee for the Space Tracking Ship. This paper analyzes the data quality of the current constellations of the Beidou satellite navigation system in China at sea,and on this basis,analyzes in detail the use of the Beidou satellite navigation system for kinematic precise point positioning services at sea. The results show that the present Beidou regional navigation system can realize the decimeter level marine kinematic precise point positioning. |
