Understanding international GNC hardware trends

摘要

An industry wide survey of GNC sensors, namely star trackers, gyros, and sun sensors was undertaken last year, in which size, mass, power, and various performance metrics were recorded for each category. A multidimensional analysis was performed, looking at the spectrum of available sensors, with the intent of identifying gaps in the available capability range. Mission types that are not currently well served by the available components were discussed, as well as some missions that would be enabled by filling gaps in the component space. This paper continues that study, with a focus on reaction wheels and magnetometers, as well as with updates to the listings of star trackers, gyros, and sun sensors. Additionally, a framework for making the database available to the community at large, as well as the continued maintenance of this database and the analysis of its contents, is discussed.
