Investigation of the rotational motion stability of the aist small spacecraft prototype according to the measurements of the earth’s magnetic field

Abstract

Abstract The paper deals with the rotational motion stabilization of the AIST small spacecraft prototype under the influence of a magnetic moment. According to the measurements of the Earth’s magnetic field by onboard measuring instruments, the angular velocity of small spacecraft rotation has significantly decreased over several years of active existence in a near-earth orbit. At the same time, attempts to actively control the angular velocity by magnetic executors were unsuccessful. In this investigation, approximate solution regions for the magnetic moment are obtained from the condition of the rotational motion stability around the center of mass of the AIST small spacecraft prototype. These regions can be further analyzed for compliance with the operation of the onboard equipment of a small spacecraft.
