Modeling and Analysis of Ultra-Low Frequency Dynamics of Drag-Free Satellites

This paper aims at deepening our understanding of the dynamics performance of the drag-free satellite at ultra-low frequency. A coupled modeling of dynamics which incorporate orbit dynamics, environment disturbance and interaction between the satellite and the proof mass is presented. Frequency bandwidth under investigation is extended from the micro-vibration frequency bandwidth (10 mHz to 100 mHz) to a broader bandwidth (0.1 mHz to 100 mHz)...
