| Abstract: | In this paper,several present methods on velocity accuracy measurement of antenna pointing had analyzed and a noncontact measurement method had proposed.This method as a new measurement way can be used to settle the difficulties on the pointing accuracy and velocity stability measurement for particular mechanism.Using this method,the measurement test and data analysis had performed for an antenna pointing mechanism and the results shows the proposed method is simple and effective. |
