Embodiment Construction

[0024] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the present invention uses a momentum wheel to quickly maneuver with a large-angle yaw attitude. The specific implementation process is as follows:

[0026] (1) The satellite works in the normal mode, and the momentum wheel is used on the satellite to autonomously control the yaw attitude. When this method is used, the ground control station first remotely sends the command to prohibit the autonomous control of the yaw attitude on the satellite and stop the autonomous control of the yaw attitude on the satellite. , Controlled by the ground instead.

[0027] (2) The ground control station remotely sends an instruction to prohibit the on-board autonomous yaw gyro calibration and stop the on-board autonomous yaw gyro calibration.

[0028] (3) The ground control station remotely sends instructions to stop the...

Abstract

The invention discloses a method for maneuvering large-angle yaw attitudes by the aid of momentum wheels. The method has the advantages that existing yaw attitude offset ability of an onboard control subsystem is utilized and is combined with a ground remote control process, offset target quantities are repeatedly injected by the method at multiple steps, and a control procedure with a high offset quantity is divided into a plurality of control procedures with small offset quantities, so that large-angle yaw is finally maneuvered via the multiple control procedures with the small offset quantities; the method is smart in design, simple in implementation and reliable in running, and actual requirements of capturing positions of inclined orbit satellites during flight control and keeping the inclined orbit satellites at in-orbit positions for a long time can be effectively met on the premise that onboard software is not modified.

Description

Technical field [0001] The invention relates to a method for fast and large-angle yaw attitude maneuvering using momentum wheels, and is suitable for the field of satellite attitude control. Background technique [0002] Navigation IGSO / MEO satellites are affected by orbital perturbation and require orbital position maintenance operations. According to the results of simulation calculations, the yaw attitude of IGSO / MEO is often in a period of large-angle offset during position holding, and position holding generally requires the yaw angle to be around 0° or 180°, so a wide range of adjustments are required before position holding operations Yaw attitude. [0003] The amount of orbit control jet required to maintain the normal position is very small. If the jet is used to adjust the yaw attitude before orbit control, it will have a greater impact on the orbit of the satellite and greatly affect the accuracy of orbit control. [0004] Therefore, the commonly used satellite yaw attit...
