Design methods of planar magnetic actuators for small satellites attitude control systems

To ensure the orientation of small spacecraft, compact magnetic coils based on a printed circuit board are used. In this paper, we propose a method for calculating the geometry of such coils based on the available space on a printed circuit board, as well as a method for calculating the parameters of the resulting coils. Examples of calculations are given and it is shown that the use of complex geometry can give a significant increase in the magnetic moment in comparison with round coils on the same printed circuit board.
