Embodiment Construction

[0011] combine figure 1 , the present invention includes a control center, a first cooperation target and a second cooperation target, and verifies the feasibility of the orbit change control scheme and mission control control scheme of the space cooperation mission through the first cooperation target and the second cooperation target. The first cooperation target and the second cooperation target include the same unit composition, including a positioning camera, a pose camera, a free base, a task execution mechanism, a free base positioning unit, an orbit control unit, a relative pose measurement unit, and a mission control unit. unit, communication unit.

[0012] The following takes the first cooperation goal as an example to introduce the functions of each unit in detail.

[0013] Positioning camera: point vertically to the ceiling, observe the positioning feature points on the ceiling, and transmit the image information to the free base positioning unit.

[0014] Pose c...

Abstract

The invention discloses a free base space cooperation task motion reappearance experiment system, and belongs to the field of space mission ground validation. In order to overcome the shortcoming that an existing space cooperation task ground validation system cannot simulate orbital motion of a spacecraft, orbital motion of the spacecraft is simulated by a free base, and a task execution mechanism is mounted on the free base and used for finishing cooperation tasks. The complete process of the space cooperation tasks from long distance navigation, orbital maneuver, target approaching to final task execution can reappear on ground motion, and feasibility of an orbital maneuver control scheme and a task control scheme is verified.

Description

technical field [0001] The invention belongs to the field of ground verification of aerospace missions, and in particular relates to an experimental system that can be used for ground verification of the feasibility of orbit change control schemes and mission control schemes of space cooperation missions. Background technique [0002] Space cooperation tasks involve the coordination of multiple spacecraft to complete specific tasks, including various on-orbit services such as rendezvous and docking, on-orbit fuel transfer, on-orbit module replacement, and on-orbit assembly, as well as the supply and repair of space stations, etc. The category of space cooperation missions. In recent years, the research on space cooperative missions has been rapidly developed and widely used, and has become a hot spot in the development of the world aerospace industry. The Japanese Engineering Experimental Satellite-7 program (ETS-VII), launched in November 1997, implemented tasks such as on...
