A method and system for minimizing the solar array sun tracking disturbance is
disclosed. The method separates the North solar array wing stepping and South solar
array wing stepping in time, and use the disturbance caused by one solar array
wing to cancel the disturbance caused by the other solar array wing. It separates
the step times of these two solar arrays by a half cycle of the array frequency
excited by the solar wing drive stepping. Because of the symmetry between the North
and South solar arrays, their disturbances cancel each other out.
