On-Orbit Magnetometer Data Calibration Using Genetic Algorithm and Interchangeability of the Calibration Parameters

Magnetometers are important sensors with applications in the attitude determination and control systems of satellites. CubeSats have certain limitations related to power, mass, volume. Due this, CubeSat magnetometers not separated from other electrical circuits inside satellite. Thus, it is calibrate magnetometer, simulating operating conditions while satellite running before launch. However, due limited facilities, every able its properly on ground. This study focuses calibration on-orbit magnetometer data observed by BIRDS-3 a genetic algorithm. High oscillations total magnetic field were found measured CubeSats. Nine unknowns, scaling factors, non-orthogonal angles, offsets identified paper discusses factors that affect high data. For calibration, we used similar those model field, as deviation smaller. presents accuracy determining unknowns using algorithm, well interchangeability answers additional orbit same method can be future or after
