Visiting Spacecraft Rendezvous and Docking Information Management Technology and Application

During the rendezvous and docking of visiting spacecraft, the interactive information has very high real-time, ship station collaboration and security requirements. It is difficult to meet the requirements by relying on the ground to judge the status and uplink control commands, and it is necessary to achieve rapid data exchange and automatic collaborative control. In order to solve the problems of mutual communication and internal automatic control, based on the design concept of ship station integration, networking, and autonomous collaboration, the space station and visiting spacecraft have designed air-to-air communication and docking bus interaction technology in the information management solution, enabling the information systems of the two spacecraft to be integrated during rendezvous and docking, achieving a range of is from control information generation to terminal action execution, this ensures the rapid, accurate, and reliable collaborative control of the ship station during the rendezvous and docking process. During the development process, equivalent verification tests for rendezvous measurement and docking data were designed, and ground tests were passed. This article summarizes the above technologies and verification methods, which can serve as a reference for the future development of spacecraft technology.
