New Analytical Methods for Simulation/Estimation of Asymmetric Satellite Dynamics.

Abstract

The classical solution for the torque free motion of an asymmetric rigid body is summarized. The branched nature of this solution and the singularities inherent in the classical 3-1-3 Euler angle (or any 3 parameter) representation of attitude provides the impetus to search for new universal solutions. Two new solutions which are singularity free have been derived thus avoiding difficulties encountered in the classical solution. These new solutions are based on an Euler parameter representation of attitude. This once redundant four parameter set avoids geometrical singularities implicit in all three parameter descriptions of orientation. (Modified author abstract)
