Solid state, autonomous attitude estimation system
Abstract
This paper describes the means by which star tracker measurements can be used to estimate the rotational position of a space vehicle upon which the trackers are mounted. A nonlinear least squares approach is taken in which a novel method of normalizing the attitude quaternion is developed. Examples of convergence histories are included, as well as an estimate of the memory needed to hold the algorithm.
