Abstract

The invention discloses a tether dragging control ground test verification method and system, which uses a dynamics simulation system to generate attitude and orbital motion data of a target star and an active star; uses the dynamics simulation system to output the position and attitude of the target star and the active star The information-driven dual six-degree-of-freedom motion simulation system generates the position and attitude movements of the target star simulator and the active star simulator; the pulling force of the tether on the target is obtained through the three-dimensional force sensor on the target star simulator, and the target star simulation is obtained through the gyroscope. The attitude information of the sailboard and the main body is transmitted to the dynamic simulation system. After conversion, the relative state information and the force information of the target star are sent to the GNC computer for drag control law calculation, and the control commands are sent to the active star. The tether retracting device on the simulator carries out the tether retracting and retracting control. The invention is used for the ground semi-physical closed-loop test of dragging removal control after the flying net capture of the invalid spacecraft, and provides technical support for the on-orbit obstacle removal service.

Description

technical field [0001] The invention relates to the field of tethered dragging, in particular to a method and system for testing and verifying ground movement controlled by tethered dragging. Background technique [0002] The application field of space technology has been rapidly expanded in the past one or two decades. In addition to the continuous deepening of space science applications, with the rapid development of space technology, more and more spacecraft have been launched into space. There are also more and more old spacecraft malfunctioning and becoming space debris. These space debris occupy precious orbital resources and seriously threaten the safety of orbiting spacecraft. [0003] Capturing targets by flying nets and dragging targets to deorbit orbits is an emerging solution to clean up space debris, and has received extensive attention and research due to its strong adaptability and reusability. [0004] After the rope net captures the target, the active star...
