Abstract

In this paper, an estimator is derived for jointly estimating a spacecraft’s position and orientation based on measurements of photons from astrophysical signals, specifically x-ray pulsars. It is shown that the accuracy of a navigation solution using x-ray pulsars is inherently coupled to the accuracy of the attitude solution. The efficacy of the estimator is demonstrated using Monte Carlo simulations which demonstrate the relationship between attitude solution error and position solution error.
