Abstract
In recent years, the growing usage of Nanosatellites for complex remote sensing tasks has created a need for highly accurate attitude determination devices suitable for use on a small satellite. A star tracker provides a spacecraft with highly accurate pointing knowledge, and is a common choice for larger satellites with large power, mass, and monetary budgets. Nanosatellites adopt star trackers less frequently, due to high unit costs relative to typical program budgets, or relatively poor performance. The usage of commercially ubiquitous CMOS APS image sensors for a star tracker presents an avenue by which simultaneously reasonable cost and performance can be obtained. A miniaturized APS-based camera system is designed and constructed, and its performance evaluated under real night-sky conditions. Performance of the imaging system is shown to be adequate for usage in a multi-imager star tracker. The feasibility, costs, and benefits of such a tracker are discussed.
