Magnetic torquer calibrating coil and method

Abstract

The invention relates to the field of magnetic torquer measuring, in particular to a magnetic torquer calibrating method. The calibrating coil comprises a binding post, a coil winding, a pin header connector, a female header connector and a semi-annulus body coil framework. The semi-annulus body coil framework is made of non-permeability magnetic materials, and comprises two semi-annulus bodies with the surfaces carved with spiral lines, and two semi-annulus body shells with the smooth surfaces, wherein one annulus body can be formed by combining the two semi-annulus bodies, the pin header connector and the female header connector, one annulus body can be formed by the two semi-annulus body shells, and circle center axes of the two annulus bodies are collinear. The calibrating coil has the advantages that the calibrating coil can avoid the support part of a magnetic torquer, installing is convenient and rapid, and plug and play can be achieved; the calibrating method of the calibrating coil can be used under the normal temperature and normal pressure and is more suitable for the thermal vacuum environment, and calibration during the environment test of the magnetic torquer is more convenient to conduct.

Description

technical field [0001] The invention relates to the field of magnetic measurement of a magnetic torque device, in particular to a calibration coil for calibrating the output magnetic moment of a magnetic torque device and a calibration method thereof. Background technique [0002] The magnetic torquer is the main actuator for controlling the attitude of the satellite by using the earth's magnetic field. According to the control law, the magnetic torque device is passed a magnetic current of a certain size and direction to make it generate the required magnetic moment, and the torque is generated under the action of the orbital geomagnetic field, which is used for momentum wheel unloading and satellite attitude magnetic control. Therefore, it is very important to calibrate the output magnetic moment of the magnetic torque device conveniently and accurately. [0003] In addition, due to the high cost of manufacturing and launching satellites, each component of the satellite m...
