Simulation system for rendezvous and docking of spacecraft

Abstract

A simulation system for rendezvous and docking of a spacecraft comprises a horizontal support module, a target six-degree-of-freedom air bearing table, a tracking six-degree-of-freedom air bearing table, a master control module, and a monitor and display module. Actual features of weight and quality of a rendezvous and docking spacecraft can be simulated by six-degree-of-freedom air bearing tables, a six-degree-of-freedom test on a last translation closing stage can be carried out depending on actual rendezvous and docking spacecraft-mounted devices such as a docking mechanism. Compared with the prior art, in the simulation system, an indoor GPS unit module can measure positions and attitudes and transmit to the master control module and the monitor and display module in real time, the rendezvous and docking process of a spacecraft can be visually, accurately and real controlled and simulated, and the success rate of a simulation test can be raised. In addition, the simulation system can verify the rationality of a work sequence during the rendezvous and docking process of the spacecraft, the reliability and validity of the rendezvous and docking process of the spacecraft can be improved.

Description

technical field [0001] The invention relates to the field of spacecraft rendezvous and docking, in particular to a spacecraft rendezvous and docking simulation system. Background technique [0002] Spacecraft orbital rendezvous and docking and sample transfer are important links in the detection of planets, and sample transfer is based on rendezvous and docking. Therefore, before the launch of the spacecraft, it is necessary to perform simulation verification of the rendezvous and docking of the spacecraft in a real space simulation environment. Now The rendezvous and docking simulation system has the following problems in the real simulation of the actual working conditions of space rendezvous and docking: [0003] (1) The existing rendezvous and docking simulation system usually measures the relative distance between the test equipment through the measurement of the sensors of the spacecraft itself or the multi-degree-of-freedom motion device itself. The precision dynamic...

Problems solved by technology

[0003] (1) The existing rendezvous and docking simulation system usually measures the relative distance between the test equipment through the measurement of the sensors of the spacecraft itself or the multi-degree-of-freedom motion device itself. The precision dynamic measurement method is not conducive to evaluating the performance of the docking process, and lacks an accurate external measurement method that can evaluate the simulation results;

[0004] (2) The monitoring of the test process in the simulation system is often partial, lacks a monitoring and display system, and cannot display the overall situation of the simulation test system in real time, which is not conducive to visual confirmation of the simulation test process
