Abstract

The invention provides a modular attitude control unit for a satellite. The modular attitude control unit comprises a shell, a momentum wheel and a magnetic torquer, wherein the surface of the shell comprises at least one standard interface; the modular attitude control unit is connected to other functional modules of the satellite through the standard interface; the momentum wheel and the magnetic torquer are arranged in the shell; the momentum wheel is used for controlling the attitude of the satellite to maintain the angular momentum of the system; and the magnetic torquer is used for performing attitude control or momentum wheel unloading management on the satellite.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a modular attitude control unit for satellites. Background technique [0002] The attitude control system of the satellite is mainly used to control the attitude of the satellite so that it meets the working requirements of the satellite. Satellite attitude control includes passive attitude control and active attitude control. Among them, active attitude control refers to the way of forming control commands through attitude errors, and then generating control torque to realize attitude control, which belongs to the closed-loop control system. [0003] Most satellites need to control three mutually perpendicular axes during flight, which is called three-axis attitude stabilization. To achieve this goal, attitude sensors, attitude controllers and attitude actuators are usually required to cooperate together. In existing satellites, the attitude sensors, attitude controllers an...
