Provided in the invention is a ground simulation system for a spacecraft equipped with space manipulators. The ground simulation system comprises a linear motion base, a satellite body motion simulator, a cable follow-up system, a satellite relative measurement system, a space manipulator system and a controller. The linear motion base is used for simulating the motion orbit of a spacecraft; the satellite body motion simulator is used for simulating the six-degree-of-freedom motion of satellite space; the satellite relative measurement system is used for simulating relative measurement of a target satellite by a measurement spacecraft; the space manipulator system is used for simulating the dynamic tracking and capturing of a moving target; and the controller is used for carrying out statemanagement, data acquisition, and processing on the satellite body motion simulator, the satellite relative measurement system and the space manipulator system as well as carrying out establishment and download of different control models. With the physical simulation of the recognition ability and catching ability of the spacecraft, the measurement error, control error and execution error of thespacecraft can be reflected effectively; and full-process testing and performance evaluation can be carried out on the spacecraft effectively.
Description
technical field [0001] The invention relates to the technical field of space vehicles for on-orbit maintenance of faulty satellites, in particular to a ground simulation system for space vehicles equipped with space manipulators. Background technique [0002] The failure of an in-orbit satellite will affect its performance. Therefore, it is necessary to develop a space control aircraft equipped with multiple manipulators that can perform on-orbit maintenance tasks to carry out on-orbit satellite repair work. This has become the main direction for the development of intelligent satellite systems in the aerospace powers. [0003] Due to constraints such as ground gravity, air resistance, and large-scale movement of six degrees of freedom in space, it is usually difficult for an actual space-controlled aircraft to perform a full-state test of the control task on the ground. Instead, mathematical simulation is used for numerical simulation. However, the detection and identifica...
