摘要

A star tracker operating inside the atmosphere requires stellar atmospheric refraction (SAR) correction with rapidness, autonomy, and accuracy to promote its attitude determination. To meet this demand, a joint estimation of the SAR and star tracker attitude (STA) is proposed in this article. An SAR model involving the equivalent refractive coefficient (ERC) and the true zenith distances (TZDs) of...
