PanelSat® MSU (Mass Switching Unit)

© PanelSat GmbH i.Gr.

Orphee et al. describe in their paper the NASA NEA Scout spacecraft which shall autonomously manage the spacecraft momentum with center of mass (cm) movement through the newly developed AMT unit. PanelSat’s MSU-units are pairwise attached at the spacecraft rim, and they move masses up- or downwards in relation to the satellite bodies plane.
