Technical Session VII: Opportunities, Trends and Initiatives
Abstract
This paper provides a comparative case study detailing parallel experiences with both a modified commercial off-theshelf lens and a custom lens for small satellite applications. These lens designs were employed in two successive hardware generations of the ST-16 star tracker. The two designs are compared experimentally, measuring effective aperture, photometric efficiency, point-spread function and thermal stability. We show that opting for custom optical design can effectively remedy deficiencies in performance but often at the expense of technical and budgetary risks.
