SATELLITE LIBRATIONS

W. B. Klemperer

Peer Reviewed

Abstract:	On board a satellite vehicle everything appears weightless and therefore one would expect that passive ponderometric devices such as accelerometers, pendulums or balances would be quite useless, and that there is no easy way to determine the direction of the vertical radius vector from the central body around which the satellite is orbiting. Yet the Moon has been known for centuries to show essentially the same face to the inhabitants of the Earth (except for small oscillations called libratiolzs). A stabilizing effect must have been at work to produce this situation.
