Development of a Model of Magnetic Disturbances from Structural Elements of a Small Spacecraft and Investigation of Their Influence on the Orientation and Stabilization System

Resumo

The results of theoretical work on addressing the effects of magnetic disturbances in the engineering development of an attitude control system of a microsatellite are presented. Magnetic disturbances were calculated using the finite element method. Their influence on the control system was evaluated by integrating numerically the differential equations of the orbital and controlled rotational motion of the spacecraft. The magnetic field of the Earth was modeled in accordance with the IGRF-12 analytical relations.
