Foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents"
Drafting:
This document replaces GB/T 32307-2015 Spacecraft Magnetic Assessment and Control: Compared with GB/T 32307-2015, except for the structural adjustment
In addition to editorial changes, the main technical changes are as follows:
a) Added the terms "magnetic field", "magnetic moment" and "magnetic purification" (see 3:1, 3:2 and 3:14);
b) Changed “Magnetic Assessment and Control Process” and “Spacecraft Magnetic Control” (see Chapter 6, 8:2:2:2, Chapter 6,:2015 Edition)
9:2:2:2);
c) Added requirements for spacecraft magnetic test and evaluation (see Chapter 10);
d) Deleted the factors affecting spacecraft magnetic measurement (see 10:3 of the:2015 edition);
e) Added the appendix "Magnetic data of typical spacecraft motors before and after magnetic shielding" and "Tests of several special magnetic sensors in near-field analysis method"
Layout method", "Magnetic moment calibration method of ferromagnetic tooling equipment in magnetic testing", "Magnetic moment magnitude and scale classification of spacecraft", "A spacecraft

Spacecraft Magnetic Assessment and Control Methods
1 Scope
This document specifies the objectives, procedures and methods for spacecraft magnetic evaluation and magnetic control:
This document is applicable to the magnetic evaluation and magnetic control of spacecraft, and can be used as a reference for the magnetic evaluation and control of spacecraft parts and components:
2 Normative references
This document has no normative references:
3 Terms and definitions
The following terms and definitions apply to this document:
3:1
Magnetic field
A special form of matter generated by the space around magnets, electric currents, and moving electric charges, which transmits the magnetic field between real objects:
Note: The field strength that usually constitutes the magnetic moment of spacecraft products includes residual magnetic field, stray magnetic field, induced magnetic field and eddy current magnetic field:
3:2
Magnetic moment
A physical property of magnetic objects, which is a physical quantity that describes the magnetism of magnets and current-carrying coils:
Note: The magnetic moment corresponding to the field intensity source includes the residual magnetic moment, stray magnetic moment, induced magnetic moment and eddy current magnetic moment:
3:3
The magnetic field that remains when the spacecraft is not operating after the external magnetic field is eliminated:
3:4
The magnetic moment corresponding to the spacecraft's residual magnetic field:
3:5
When the spacecraft is powered on, the magnetic field is caused by the electric current:
3:6
The magnetic moment corresponding to the stray magnetic field of the spacecraft:
3:7
The magnetic field induced by the soft magnetic materials of the spacecraft under the influence of internal and external magnetic field factors:
3:8
The magnetic moment corresponding to the magnetic field sensed by the spacecraft:
