The Coordinate System Design and Implementation of the Spacecraft's Attitude Simulation based on Five Axis Turntable

The simulation turntable is an important device for the hardware-in-the-loop simulation of satellites or other spacecraft. It can simulate the movement attitude of the spacecraft in space such as roll, pitch, and yaw, and is widely applied in electromagnetic countermeasure, space shooting and other fields. This paper takes the on-orbit service spacecraft as the research object, studies the coordinate system transformation and implementation problems of ground simulation of spacecraft attitude based on the five-axis turntable, designs the coordinate system conversion process and verifies the effectiveness of the conversion process. The coordinate system conversion method studied in this paper can effectively realize the ground simulation of spacecraft attitude on the five-axis turntable, providing theoretical guidance and effective methods for solving the problems of attitude simulation in on-orbit service tasks, having more important guiding values for simulating experiments in the field of aerospace engineering such as rendezvous and docking.
