A system for compensating microaccelerations of the Aist small spacecraft

摘要

The MAGCOM equipment, installed on the Aist small spacecraft and intended for measuring the terrestrial magnetic field using two three-component magnetometers in a range of +/- 120 mu T and compensating microaccelerations of the small spacecraft by means of three orthogonally located electromagnets, is described. The measured data of magnetic fields and the operating results of the relay microacceleration-compensating mode are given. It is shown that the angular velocity of the Aist small spacecraft decreases from 2.5 to 0.2 deg/s for less than 20 min.
