Problems solved by technology
However, this solution requires an additional configuration of symmetrical extension rods. For small satellites, the structural space is relatively limited. Using this method increases the volume and reduces the reliability of the entire star, which is not universal.

The invention provides a satellite residual magnetism identification method, a satellite control device and a readable storage medium, and the satellite residual magnetism identification method comprises the steps: responding to the obtained satellite state data, and reading the control data of the last control period; calculating geomagnetic field intensity according to the satellite state data; and according to the geomagnetic field intensity, the satellite state data and the control data of the previous control period, calculating the total residual magnetic moment of the satellite according to a satellite dynamics model. According to the satellite residual magnetism identification method, the satellite control device and the readable storage medium provided by the invention, the residual magnetic moment can be accurately estimated without depending on a magnetometer and an additional magnetic measurement device under the condition of fully considering the inherent residual magnetic moment of the satellite and the moment interference brought by the switching characteristics of the magnetic torquer.
Description
technical field [0001] The present application relates to the technical field of satellite remanence measurement and calculation, in particular to a satellite remanence identification method, a satellite control device and a readable storage medium. Background technique [0002] Traditional satellites often use flywheels for attitude control. Based on the geomagnetic field, the flywheels are unloaded through magnetic torque devices to alleviate the problem of angular momentum saturation of the flywheels. Attitude control is performed by using a magnetic torque device to generate magnetic torque, which is widely used in various near-Earth satellites. For small satellites, the residual magnetic moments of various components of the satellite will generate disturbing magnetic moments in space; at the same time, for low-orbit satellites with relatively high orbits, the magnetic moment error caused by the switching characteristics is due to the high rated magnetic moment of the ma...
