The commands consisted of 90 turns for a certain length of time. Since there was a significant amount of wind, the sides of the rectangles were not expected to be the same length; however, the sides were all expected to be perpendicular since the airplane was tracking ground track. The performance was very good. All sides were perpendicular, as expected.
