Open publisher page 2 citations

Abstract

Aimed at a tracking and data realy satellite(TDRS),a dynamical model for the flexible multi-body system of the satellite is established.Influence of the motions of flexible antennas and accessories on the attitude of the satellite is calculated using the model.The results showed that the influence is only trivial and can be neglected when designing on the laws of control of satellite attitude,giving relevant analyses.
