摘要：
A high-precision attitude determination and control of the forthcoming European Gaia satellite is an essential task for the success of the whole mission. The requirements for the spacecraft's attitude require exceptional efforts in the simulation of the rotations of the satellite under the influence of continuous and randomly arising effects. This paper describes the structure of a physically-motivated noise model for simulating the attitude in a closed loop configuration. It deals with the analysis of the most important disturbing forces and torques acting on the Gaia spacecraft.
