Abstract
New developments in image sensors and optical materials have opened the door to dramatic mass and power reductions in celestial tracker design. The rapid development of active pixel sensors (APS) has provided a new detector choice offering high on-chip integration of support circuitry at reduced power consumption. Silicon-carbide optics are one of the new developments in low-mass optical components. We describe the celestial tracker needs of an Autonomous Feature and Star Tracking (AFAST) system designed for autonomous spacecraft control. Details of a low-mass celestial tracker based on a low-power APS array and optimized for an AFAST system are discussed.
