Mobility analysis of the large adaptive reflector antenna reflector

The motion of the three-tethered balloon system in the large adaptive reflector antenna is analyzed. First, the motion scale of the balloon in the sky is investigated, which is composed by three different spherical surfaces. Second, different materials always cause different static and dynamic deformation of the tether, so the affect of the material to the stability of the motion of balloon is discussed by using the scaled-down model for laboratory use. Third, the influence of the motion pattern of each tether to the motion stability of the balloon is given.
