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...

Abstract

Provided is a control system working mode setting and switching method based on information fusion. An existing method that a control system working pattern and mode is designed according to functions and the using conditions of a sensor is converted to a method that the control system working pattern and mode is determined according to the functions. The working pattern is designed as a sun capturing and cruising pattern, an earth capturing and pointing pattern, an apogee pattern, a position keeping pattern and a normal pattern (including a normal working mode, a counteractive wheel disassembling working mode, a north and south position keeping working mode and an east and west position keeping working mode). The patterns can be autonomously switched on a satellite or be switched in a remote-control mode from the ground. According to the method, pattern designing and switching conditions are optimized, the number of control patterns is reduced, conversion relation between the patterns is simplified, complex degree of ground observation and control is lowered, the using number of software codes is lowered, and the performance of a control system is improved.

Description

technical field [0001] The invention relates to a satellite control method, in particular to a working mode setting and switching method of a high-orbit satellite control system. Background technique [0002] High-orbit satellite control systems are usually divided into control modes and methods according to flight tasks and sensor usage. The working modes are: sun capture (SAM), earth search (EAM), earth pointing (EPM), apogee (AFM), position preservation (SKM), Transition (TRM), Normal (NM), Antenna Pattern Mode (ANM), Sloped Orbit Mode (SLM), Hardware Failure Earth Pointing Safe Mode (ESM), Software Failure Earth Pointing Safe Mode (ETM) ). [0003] The same working mode is divided into several different working modes according to the different composition of the control system sensor or the different offset. The change of the working mode can be controlled autonomously by the satellite or by remote control on the ground. [0004] Due to the limitation of the service l...
