Spacecraft rendezvous and docking device and method

Abstract

The invention provides a spacecraft rendezvous and docking device and method. Images of at least three light sources in the spacecraft rendezvous and docking device are obtained by an image obtainingdevice in the spacecraft rendezvous and docking device; according to the obtained images, information of the relative position between the image obtaining device and a target spacecraft is obtained, and therefore a tracking spacecraft can be automatically guided to an initial aiming point of the target spacecraft based on the information of the relative position; and manual adjusting links can beomitted at the final approaching stage and parking and docking stage during mutual docking, the tracking spacecraft can be precisely aligned with the initial aiming point of the target spacecraft through an automatic aligning mode, the success possibility of rendezvous and docking is increased, and thus docking safety is improved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft, and more specifically relates to a spacecraft rendezvous and docking device and method. Background technique [0002] With the continuous development of aerospace technology, rendezvous and docking plays a vital role in the docking process of the target spacecraft and the tracking spacecraft. Through rendezvous and docking, the interactive identification between the target spacecraft and the tracking spacecraft and the tracking spaceflight can be realized. positioning of the target spacecraft. At present, the rendezvous and docking includes four stages: ground guidance, short-distance guidance, final approach, and docking and docking. The working process between the target spacecraft and the tracking spacecraft in these four stages is as follows: [0003] In the ground guidance phase, the tracking spacecraft undergoes several orbit-changing maneuvers with the support of ground measurement and...

Problems solved by technology

[0007] However, in the above-mentioned stages of interactive docking, such as the final approach stage and the docking and docking stage, the astronauts need to adjust the tracking spacecraft according to the relative position of the tracking spacecraft and the target spacecraft so that it is aligned with the initial aiming point. There may be a certain deviation in this manual alignment method, which will lead to the failure of interactive docking and reduce the safety of docking
