This paper deals with dynamics modeling for Tracking and Data Relay Satellite (TDRS) with several flexible appendages and a liquid fuel tank. The basic parameters for the equivalent mechanical model under low gravity are presented when the pendulum motion of the tank is small enough such that it can be approximated linearly. Hybrid coordinate is used to describe the configuration of the TDRS, and the D'Alembert principle in virtual work is employed to derive the dynamics equations. The equations obtained are simple and common, which can be applied to describe many complicated open chain spacecraft systems.
