Short summary
This paper presents a gravity unloading facility to simulate micro-gravity environment of space. The facility unloads the gravity of artificial antenna of satellite and its pointing mechanism to test the performance of the pointing mechanism on the ground. The facility consists of two layers to unload gravity hierarchically and simultaneously while the antenna pointing mechanism consists of two joints. The calculation, simulation and experiments all show the effectiveness of the method applied.
