Relative orbit design and high-precision posture pointing control method aiming at space non-cooperative target

The invention discloses a relative orbit design and high-precision posture pointing control method aiming at a space non-cooperative target, and relates to a relative orbit design and a high-precision posture pointing control method. The problems that the orbit control is difficult and the posture pointing precision is influenced in orbit posture coupling control when the track position is limited in the prior art are solved. The method comprises the following steps: tracking a flying over track design of a relative space non-cooperative target spacecraft of a spacecraft; tracking a shifting track design of the relative space non-cooperative target spacecraft of the spacecraft; and tracking a posture controller design of the relative space non-cooperative target spacecraft of the spacecraft, namely, finishing the relative orbit design and the high-precision posture pointing control method aiming at the space non-cooperative target. The method disclosed by the invention is applied to the field of the space spacecrafts.
