Design and Verification of Joint Closed-loop Test Mode for Rendezvous and Docking Multiple Spacecraft

In the field of manned spaceflight, multi spacecraft rendezvous and docking technology is the key and difficult problem of development, and the importance of the design of closed-loop test system is particularly prominent. The design and implementation of joint closed-loop test of multi spacecraft for rendezvous and docking realizes the integrated real-time dynamic synchronous electrical test of multi spacecraft, realizes the timing synchronization and sensitivity of multi spacecraft and its test system The dynamic model of the simulator and the mechanical and electrical system is driven synchronously and dynamically in real time. The automatic test of the integrated real-time precise control of multiple spacecraft and the real-time unified management of the multi-channel and large loop information flow between multiple spacecraft are adopted. To solve the problem of the verification of the interaction state of multiple spacecraft in the mission phase, and present the whole process of rendezvous and docking flight on the ground, so as to achieve the purpose of joint electrical measurement of multiple spacecraft.
