Popis: | This paper considers the problem of jointly estimating the attitude and spin rate of a spinning spacecraft. Psiaki has formulated a family of optimization problems that generalize the classical least-squares attitude-estimation problem, known as Wahba’s problem, to the case of a spinning spacecraft. In the special case where the rotation axis and the fundamental sampling period are fixed and known, but the spin rate is unknown (such as for nutation-damped spin-stabilized spacecraft), Psiaki’s problem can be reformulated exactly as a type of tractable convex optimization problem called a semidefinite optimization problem. This reformulation allows the problem to be globally solved using standard numerical routines for semidefinite optimization. |
