Incorporation of orbital kinematics and the gravity-gradient force field in flexible spacecraft dynamics models / author: P.C. Hughes ; prepared by: Dynacon Enterprises Ltd. : Co24-3/1-83-052E-PDF
"Previous reports in this series have treated the dynamics of flexible spacecraft as though the reference orientation was inertially fixed (i.e., not rotating). This is a very good approximation because, although the reference orientation is not precisely inertial, it is 'Earth-pointing' and thus rotates once per orbit. For geostationary communications satellites this represents a rotation of the reference orientation of 2n radians every 24 hours - virtually negligible compared to the circular frequencies of flexible spacecraft modes. Nevertheless, in this report the extra terms associated with the 'inertial force field' caused by the once-per-orbit reference motion are calculated as an extension to the general theory"--Summary, page iii.
