某型號衛(wèi)星磁性分析與控制

Magnetism analysis and control for a satellite

摘要: 某型號衛(wèi)星的有效載荷之一高能望遠鏡對磁場敏感，因此在設(shè)計階段即需分析衛(wèi)星在軌時載荷所處的磁場環(huán)境，并盡可能提高載荷的抗磁場干擾能力。文章根據(jù)衛(wèi)星的構(gòu)型，對整星的磁場分布進行了計算；對載荷的抗磁場干擾能力進行了測試；對載荷的磁屏蔽方案進行了仿真與測試；分析了抗磁場干擾設(shè)計對整星磁性控制的影響，證明衛(wèi)星可以滿足總磁矩不大于5.0 A?m2的姿態(tài)控制要求。

Abstract: High energy telescope is an important payload of a certain satellite and it is sensitive to magnetic field. Therefore, its design requires an analysis of the magnetic environment while the satellite is on the orbit in order to better counteract the magnetic disturbance. In this paper, the magnetic distribution about the satellite in accordance with its structure is calculated, the payload’s ability to counteract magnetic disturbance is analyzed, and the schemes of load’s magnetic shielding are compared.
