Embodiment Construction

[0037] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0038] The invention discloses a method for judging the yaw maneuvering timing of an inclined orbit satellite. The on-board information is input to autonomously decide whether to perform a yaw maneuver, and to determine the moment to start the yaw maneuver.

[0039] Such as figure 1 As shown, it is an embodiment of a method for judging the yaw maneuver opportunity of an inclined orbit satellite according to the present invention, and the method includes the following steps:

[0040] Step 1. List all constraints affecting yaw maneuvers.

[0041] When satellites in inclined orbits autonomously perform yaw attitude maneuvers, the constraints that need to be considered can be divided into internal constraints and external constraints.

[0042] The internal constraints are mainly the constraints caused by the current environment and the object...

Abstract

The invention discloses an inclined orbit satellite yaw maneuvering opportunity judgment method. The method comprises the steps that inclined orbit satellite yaw maneuvering constraint conditions are determined and judgment threshold values of the constraint conditions are determined; according to the constraint conditions and the judgment threshold values of the constraint conditions, the yaw maneuvering opportunity is judged. According to the inclined orbit satellite yaw maneuvering opportunity judgment method, the inclined orbit satellite in-orbit automatic yaw maneuvering constraint conditions are comprehensively analyzed, the property of the yaw maneuvering constraint conditions is analyzed, conditions and the requirement for the occurrence frequency are met, and the effective and reliable basis is provided for accurately judging the yaw maneuvering opportunity and time; the yaw maneuvering opportunity judgment criteria and the yaw maneuvering starting specific time judgment method are provided, and satellite-borne software can accurately and automatically carry out yaw maneuvering starting and control.

Description

technical field [0001] The invention relates to a satellite control technology, in particular to a method for judging the yaw maneuver timing of an inclined orbit satellite. Background technique [0002] The complexity of the in-orbit illumination situation of inclined orbit satellites is the difficulty of satellite development. By designing the autonomous yaw maneuver control strategy, the satellite can adapt to the complex illumination conditions of the inclined orbit. The key to the autonomous yaw maneuver of the satellite in orbit is to choose the correct and reasonable yaw maneuver timing to start the yaw maneuver. The process of selecting the timing of yaw maneuver is the process of judging whether the constraints are satisfied. Therefore, it is necessary to comprehensively analyze the various constraints affecting the yaw maneuver, and choose the timing of the yaw maneuver reasonably, not only to ensure that the maneuver window will not be missed, but also to ensure...
