Embodiment Construction
[0029] With the continuous improvement of the software and hardware performance of the satellite computer in recent years, the gradual maturity of the long-life star sensor and the long-life gyroscope, the configuration reliability of the attitude sensor of the control subsystem has also been enhanced accordingly. In the design, the attitude determination technology of information fusion has created the conditions, and then provided the foundation for the design of the new control system mode.
[0030] like figure 1 As shown, it is a schematic diagram of the method of the present invention. Based on information fusion, the method of the present invention changes the existing work mode and mode of the control system divided by function and sensor usage to be divided into work mode and mode by function, and the control system is set to five work modes: sun capture and cruise mode, Earth capture and pointing mode, apogee mode, position hold mode, and normal mode. The modes can b...
