Optimal Design of Tracking Channel Switching for S-band Unified TT&C System of Space Tracking Ship

The measurement beam of the S-band unified TT&C system of the surveying ship is wide, and the guiding antenna has no obvious effect. Therefore, after the measurement and control system of the tracking ship is overhauled and rebuilt, the guiding antenna will be removed, and the tracking channel of the original guiding antenna will be replaced by the second tracking channel of the main antenna channel, thus realizing the fast switching of the measurement channel of the servo system. In the actual data processing and interaction process, the switching of the measurement channel of the servo system will affect the data processing accuracy of the master computer system due to the difference in the photoelectric deviation values bound by the master computer system, thereby affecting the measurement data sent by the final measurement ship to the mission center and the accuracy of the orbit determination data. In view of the above situation, this paper designs a set of optimization strategies, which realizes the adaptation and compatibility of the central computer system to the fast switching tracking channel of the servo system, and also realizes the adaptation and compatibility of the multi-target tracking strategy.
