Magnetic Cleanliness Activities in Advanced Nanosatellites Systems for Earth Observation Research - Anser Mission

The purpose of this paper is to describe the specific magnetic measurements that must be made on the flight model ANSER (Advanced Nanosatellites Systems for Earth observation Research) satellite to ensure the necessary magnetic cleanliness, to characterize the magnetic torques, and to verify the magnetometer measurements. The objective is to develop the necessary technology to implement future space missions based on Satellite Constellations. This article describes both the innovative measurement procedures used and the measurement uncertainty calculations. The results obtained from both Cube Sats and the most important magnetic elements are presented, including the determination of the remaining and induced magnetic moment of spacecraft, and the calibration or characterization of magnetometers and magnetic torquers.
