The invention relates to a spacecraft three-super-control broadband multi-source multi-level cooperative attitude determination method and system, which solves the problem of relative attitude measurement when the measurement sensor is difficult to provide a large-scale maneuver in the process of spacecraft pointing control, and is suitable for space The line of sight is directed to the field of control. On the basis of the relative orbital motion equation, the relative position vector and velocity vector of the tracking spacecraft and the target spacecraft are obtained by filter estimation. The two-vector attitude determination method is used to establish the target pointing attitude, and the line-of-sight angular velocity information of the tracking spacecraft pointing to the target spacecraft is obtained through filtering estimation, so as to provide accurate relative attitude and line-of-sight angular velocity information for the spacecraft attitude pointing control system.
Description
A method and system for cooperative attitude determination of spacecraft with three-super-control broadband multi-source and multi-stage technical field The invention belongs to the field of spacecraft attitude control, relate to a kind of coordination of a kind of spacecraft three super-control broadband multi-source multi-level The attitude determination method and system can effectively solve the prediction and estimation of target attitude information in the process of high-precision attitude pointing of spacecraft. count. Background technique [0002] The current spacecraft has proposed three requirements for pointing control (ultra-high precision, ultra-high stability, and ultra-agility). Technology has been unable to meet the requirements. During the observation mission, the optical payload in the spacecraft is required to be able to point to the desired attitude and progress. High-precision attitude tracking and maintaining control to obtain clear and stable t...
