Abstract
A system and method for correcting pointing errors induced by an inclined orbit ( ) for a satellite ( ) that is adapted to be in an orbit having zero inclination ( ). The present invention generates a yaw correcting cosine rate command ( ) that is integrated ( ) by a steering law having input parameters dependent upon the angle of inclination, &THgr;, to derive a sinusoidal yaw offset. The present invention also generates a roll correcting cosine rate command ( ) that is integrated ( ) according to a steering law having input parameters dependent upon the angle of inclination, &THgr;, to derive a sinusoidal roll offset.
