Study and selection of coil pa rameters for NTUU«KPI» microsatellite

Abstract

Microsatellite motion relative to the center of mass (rotational motion) is much more sensitive to external perturbations than the motion of the center of mass along the trajectory, which does not notice them at all. That is why angular motion control of the microsatellite, or, in other words, control systems relative to the center of mass, is as a rule the most difficult and crucial part of the onboard equipment. The efficiency of the MS and, consequently, efficiency of practical tasks they perform significantly depends on the functionality of these systems, as well as their technical and operating characteristics. Performance of the «KPI» microsatellite when using the system control unit — magnetic coils for space orientation of microsatellites is defined. For the microsatellite to have the correct orientation, it is necessary to select such parameters to be able to manage the current supply in the coils proportionally to the required rotation in space. The research data and results obtained are used in designing on board systems of spacecrafts.
