Embodiment Construction

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments disclosed in the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0066] Such as figure 1 , in this embodiment, the convenient solar sensor on-orbit health monitoring method includes:

[0067] Step 101, according to the current working mode of the satellite, it is judged whether the preset on-orbit health monitoring start condition is satisfied.

[0068] In this embodiment, firstly, a set M containing all working modes of satellites can be constructed; then, from the set M, the working modes with reliable output of the sun sensor can be screened to obtain the subset M1; finally, the current working mode of the satellite can be obtained mode, and judge whether the current working mode of the satellite belongs to the subset M1. Wherein, if the current working mode of the satellite belongs to the subs...

Abstract

The invention discloses a convenient sun sensor in-orbit health monitoring method and system, and the method comprises the steps: judging whether a preset in-orbit health monitoring starting condition is satisfied or not according to a current working mode of a satellite; if it is determined that the preset on-orbit health monitoring starting condition is met, starting on-orbit health monitoring, and executing digital sun sensor on-orbit health monitoring, fixedly-installed simulation sun sensor on-orbit health monitoring and on-sailboard simulation sun sensor on-orbit health monitoring sequentially; and outputting the obtained on-orbit health monitoring result of the digital sun sensor, the on-orbit health monitoring result of the fixedly mounted simulated sun sensor and the on-sailboard simulated sun sensor as comprehensive monitoring results. The problems that the measurement and control arc section of a low-orbit remote sensing satellite is short, and fault diagnosis of the sun sensor is not timely are solved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft attitude control, and in particular relates to a convenient on-orbit health monitoring method and system for solar sensors. Background technique [0002] The sun sensor is an important single unit of the satellite control system, but because the measurement accuracy of the sun sensor is not as good as that of the star sensor, the traditional two-vector attitude determination method of infrared sensor + sun sensor has been less and less used in orbit. Therefore, the sun sensor is usually no longer introduced in the normal working mode of existing satellites, but only plays a role when the satellite is abnormally aligned with the sun. [0003] If the sun sensor is abnormal in orbit, since it does not affect the normal operation of the satellite, the failure cannot occur through the main working state of the satellite. Moreover, the output of the sun sensor in the sunny area usually has the chara...
