The magnetic cleanliness of a satellite Based on optimum placement of equipment using PSO

Magnetometer is one of the most sensors due to its lightness and low power consumption in satellites. Therefore, the magnitude of the magnetic field at the location of the magnetometer should be less than the magnetic cleanliness characteristics defined for the satellite. One of the best solutions is to properly placement included position and angular position of the equipments in such a way the magnetic field is minimized at the magnetometer location. In this paper, a cost function is defined based on the norm of the magnetic field generated by the equipments at the magnetometer location, and the cost function is minimized by adjusting the angular position of the equipments using the particle swarm optimization (PSO) algorithm. Position adjustment compensates the generated magnetic field and helps to passively achieve the magnetic cleanliness characteristics of a satellite. Finally, by simulating the magnetics of a satellite equipments, the performance of the algorithm in achieving magnetic cleanliness is shown.
