Abstract

The invention provides a magnetic moment self-adaptive dynamic testing method for a spacecraft and its products, comprising: setting the status of the spacecraft and its products, arranging product magnetometer sensors and background magnetometer sensors; rotating a non-magnetic turntable for data collection and abnormal elimination; calculate the background magnetic induction intensity; calculate the product magnetic induction intensity; calculate the magnetic moment value of the spacecraft and its products. The invention solves the problem of accurately testing the magnetic moment of the spacecraft and its products through the method of self-monitoring and eliminating the background magnetic field in the geomagnetic environment, approximately simulating the zero magnetic environment with a relatively economical method.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a magnetic moment self-adaptive dynamic testing method of a spacecraft and its products. Background technique [0002] When a low-Earth orbit spacecraft is in a geomagnetic environment, the magnetic moment of the spacecraft will generate a magnetic interference moment, which will affect its on-orbit attitude. In addition, if the magnetic moment is large, it will also have a certain impact on the electromagnetic compatibility of the spacecraft. Therefore, when developing on the ground, it is generally necessary to measure the magnitude and direction of the spacecraft's residual magnetic moment. [0003] The main magnetic moment of a spacecraft is composed of three parts: permanent magnetic moment, magnetic induction moment and stray magnetic moment. The induction moment generated by the orbital geomagnetic field does not constitute the disturbance moment of attitude control. ...
