[0277] Based on the evaluation method and evaluation system proposed above, we take the evaluation of the state of health of the satellite attitude control system as an example. The main steps are as follows (for other details, refer to the specific implementation above):
[0278] (1) Construct the system structure tree of the satellite attitude control system and determine the working logic, such as Figure 8 As shown, take the sensitive organization sub-system in the system structure tree as an example to expand the description:
[0279] (i) The pitch and rolling horizon instruments are connected in parallel to form an horizon instrument component;
[0280] (ii) The X-axis magnetometer, Y-axis magnetometer, Z-axis magnetometer and backup magnetometer form a magnetometer assembly in a (parallel + redundancy) relationship;
[0281] (iii) X-axis gyroscopes, Y-axis gyroscopes, Z-axis gyroscopes and obliquely mounted gyroscopes form gyroscope components in a (series + redundancy) relation...
