A control method of antenna pointing error due to orbital inclination for a spin-stabilized satellite
Abstract
A method is developed to remove the antenna pointing error due to increased orbit inclination for a spin-stabilized satellite with a despin antenna, after the orbit plane control becomes impossible because of fuel shortage. This method can be used to keep the satellite antenna pointing error within a permissible range by adjusting the satellite attitude and antenna despin bias under such conditions. Results are presented of experiments carried out using the Medium Capacity Communications Satellite for Experimental Purposes in order to measure the diurnal carrier power to noise power density ratio variation of the overall K-band (30/20 GHz) satellite link. It is determined that this method is effective for reducing the satellite antenna pointing error under these conditions.
