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 rendezvous and docking of spacecraft, and in particular relates to a short-distance rendezvous test method of spacecraft. Background technique [0002] The rendezvous and docking technology refers to the technology in which two aircraft meet at the same position in the orbit at the same speed at the same time and are structurally connected as a whole. The two aircraft involved in rendezvous and docking are usually a passive aircraft and an active aircraft. Passive aircraft do not do any maneuvers or do a small amount of maneuvering, known as target aircraft or target aircraft. The active vehicle performs a series of orbital maneuvers towards the target vehicle and is called a pursuit vehicle or tracker. [0003] According to the flight process, the rendezvous and docking mission is generally divided into a long-range guidance section, a short-range guidance section, a translation and approach section, a...
