Progress on the use of satellite technology for gravity exploration

Abstract

In this paper, the technological progress on Chinese gravity exploration satellites is presented. Novel features such as ultra-stable structure, high accurate thermal control, drag-free and attitude control, micro-thrusters, aerodynamic configuration, the ability to perform micro-vibration analyses, microwave ranging system and mass center trimmer are described. Keywords: Ultra-stable structure, Precision thermal control, Drag-free, Micro-thruster, K-band ranging, Aerodynamics, Micro-vibration, Gravity satellite
