Abstract
Star trackers are the most accurate attitude estimation sensor. With current advancements in small satellite technologies, the pointing accuracy requirements are increasing for both commercial and scientific missions. CubeSpec is an in-orbit demonstration CubeSat mission to unravel the interior of massive stars using asteroseismology by high-cadance monitoring of the variations in spectral line profiles. This paper examines attitude estimation strategies for a multi-star tracker ADCS for CubeSpec mission. The new methodologies are tested with both simulation and hardware-in-the-loop night sky tests. The proposed solution, improves both availably and accuracy of the attitude estimates specially during the daylight section.
