description abstract	Abstract: A jitter in the solar array drive control loop during Venus mapping operations was caused by a deficiency, at oblique sun angles, in the algorithm that is used in Flight Software (FSW) to determine whether a solar panel position correction is required. Conduct thorough reviews to verify math models of hardware and to understand the implications of simplification of math models on performance in flight. Use finer resolution display scales to identify subtle instabilities.
