A mathematical model of LANDSATD attitude dynamics with internal motion
Abstract
An algorithm to model the effects of internal motion by the solar array and the high gain antenna on the attitude of the LANDSATD spacecraft is presented. The relative torque and angular momenta arising from the internal motions are assumed to be attitude independent but are considered to be a source of attitude perturbations. The equation of motion for the three body problem is derived and then compared with the one body case. The effect of the internal motion on the control of the spacecraft is shown in a computer study of the problem.
