Abstract

The invention discloses a track control method for a space rendezvous ground guide section with limited orbit maneuvering, aiming to realize high-precision track control of the space rendezvous ground guide section under the condition of limited orbit maneuver. The technical solution is to first determine the orbital maneuvering scheme of the tracking spacecraft as five orbital maneuvering schemes, determine the orbital control parameters M1~M5 that need to be calculated; calculate the orbital control parameter M1 after the tracking spacecraft enters orbit, and upload it to the tracking spacecraft. The maneuvering system performs the first orbital maneuver; after the first, second, and third orbital maneuvers are completed, the orbital control parameters M2, M3, and M4 are calculated respectively, and uploaded to the tracking spacecraft, and the orbital maneuvering system performs the second, third, and fourth maneuvers Orbital maneuvering; finally implement the fifth orbital control according to the orbital control parameter M5 (obtained when calculating M4). The invention has less number of track maneuvers, lower requirements on the attitude control system, improves the track control accuracy of the ground guidance section under the condition of limited track maneuvers, and has fast calculation speed and good real-time performance.

Description

Orbit control method for space rendezvous ground guidance segment with limited orbital maneuvering Technical field [0001] The present invention relates to a space rendezvous orbit maneuver control method, especially a space rendezvous ground guide with limited orbit maneuvers Lead track control method. Background technique [0002] The space rendezvous and docking process can generally be divided into stages such as ground guidance, short-range guidance, translation approaching and docking. exist In the ground guidance section, the tracking spacecraft performs several orbital maneuvers with the support of ground measurement and control to reach the target spacecraft several times below. Aiming point at ten kilometers. The track control method of the ground guidance section is a key issue in the design and control of the rendezvous and docking track. The track control method of current ground guide segment mainly contains two classes: a class is special point track chan...
