Embodiment
[0171] Embodiment: Carry out the simulation analysis of 100s to the cooperative attitude determination of spacecraft three-super-control broadband multi-source multi-level that the present invention proposes, the optical camera and lidar measurement noise in the simulation are Gaussian distribution noise, consider factors such as sensor measurement delay, And the random amount of sinusoidal motion is introduced into the attitude motion to verify the adaptability of the attitude determination method to disturbance.
[0172] The relative position vector and velocity vector of the spacecraft and space moving target are obtained by filter estimation. The target pointing attitude is established by the dual-vector attitude determination method, and the line-of-sight angular velocity information of the tracking spacecraft pointing to the target spacecraft is further obtained through filtering estimation, so as to provide accurate relative attitude and line-of-sight angular velocity in...

The invention relates to a spacecraft three-super control broadband multi-source multi-stage collaborative attitude determination method and system, solves the problem that a measurement sensor is difficult to give out relative attitude measurement under a large-range maneuvering condition in a spacecraft pointing control process, and is suitable for the field of space sight pointing control. Themethod comprises the steps: on the basis of the relative orbit motion equation, obtaining a relative position vector and a speed vector of the tracking spacecraft and the target spacecraft by utilizing filtering estimation; employing a double-vector attitude determination method to establish a target pointing attitude, and obtaining the sight line angular velocity information of a tracking spacecraft pointing to a target spacecraft through filtering estimation, and providing the accurate relative attitude and sight line angular velocity information for a spacecraft attitude pointing control system.
Description
technical field [0001] The invention belongs to the field of spacecraft attitude control, and relates to a spacecraft three-super-control broadband multi-source multi-level collaborative attitude determination method and system, which can effectively solve the prediction and estimation of target attitude information in the high-precision attitude pointing process of spacecraft. Background technique [0002] At present, the spacecraft has put forward three super (ultra-high precision, ultra-high stability, and ultra-agility) requirements for pointing control, and the existing technology has been difficult to meet the requirements. During the observation mission, it is required that the optical payload in the spacecraft can point to the desired attitude, and perform high-precision attitude tracking and maintenance control to obtain clear and stable image information of the target star; and it is necessary to keep the spacecraft y The axis (solar wing) points to the sun for cap...
