Contributor Kuiper, H.J.M. (mentor) Faculty Aerospace Engineering Department Space Systems Engineering Date 2014-09-25 Abstract This Thesis report is written for the space community, specially for people interested in the field of nanosatellites, who know how star trackers work, but are unfamiliar with their operations and limitations in an earth observation mission. To introduce users to the topic, this document is primarily concerned with a single aperture star tracker in order to simplify the explanation. The general mission parameters are described and the critical requirements are flowed down to the Attitude Control System and subsequently the star tracker. Various influences on star tracker performance and availability are described, and different subsystems are analyzed in terms of system performance: optics, baffle, image sensor and on-board software. In addition, the verification process was present from the very beginning, including a verification plan and the calibration and validation activities to be performed on ground in the lab and during the commissioning phase. It is shown that a single aperture star tracker is well suited for a very limited set of operating conditions, namely a strictly nadir-pointing earth observation mission, however the flexibility and robustness of the multiple-aperture star tracker is generally required for missions with realistic operational requirements.
