Abstract

A behavior of satellite with elastic rod is investigated. The satellite moves on a near-earth orbit and it is stabilized by means of jet engines. It is known space is rather «quiet» environment in terms of vibrational loads acting on objects remaining in it. Therefore structure element stiffness can be very low for a spacecraft. Effects related with action of gravitational field gradient on the satellite are studied. The study is curried out for a small elastic displacement case. The results obtained in the paper can be valuable both for satellite control theory and applications.
