The invention relates to a spacecraft close range rendezvous test simplifying method. The spacecraft close range rendezvous test simplifying method comprises the steps of S1, establishing a relative motion relation between a target and a tracker; S2, constructing a ground test model; S3, simplifying the test model; and S4, carrying out sensor view field verification on the simplified test model. According to the spacecraft close range rendezvous test simplifying method, a problem of difficult relative motion simulation of the spacecraft in a close range rendezvous ground test can be solved. The motion, in the plane, of the tracker for tracking the mass center and the attitude of a spacecraft is simplified into one-dimensional motion of the tracker along a straight line and rotations of twoaircraft around the mass centers. Further, the motion, in the plane, of the tracker for tracking the mass center and the attitude of the spacecraft can also be simplified into rotations of the two aircraft around the mass centers in the case that the mass centers are fixed.
Description
technical field [0001] The invention belongs to the technical field of spacecraft rendezvous and docking, and in particular relates to a spacecraft close-range rendezvous test method. Background technique [0002] The rendezvous and docking technology refers to the technology in which two aircrafts are merged and structurally connected to form a whole at the same time at the same position in the orbit and at the same speed. The two aircraft participating in the rendezvous and docking are usually a passive aircraft and an active aircraft. Passive aircraft that do not make any maneuvers or do a small amount of maneuvers are called target aircraft or target vehicles. Active vehicles perform a series of orbital maneuvers towards the target, known as tracking vehicles or trackers. [0003] The rendezvous and docking tasks are generally divided into long-range guidance section, short-range guidance section, translation approach section and docking section according to the flight...
