Optimization of star research algorithm for esmo star tracker [PDF]

open access: yes, 2011
This paper explains in detail the design and the development of a software research star algorithm, embedded on a star tracker, by the ISAE/SUPAERO team. This research algorithm is inspired by musical techniques. This work will be carried out as part of the ESMO (European Student Moon Orbiter) project by different teams of students and professors from ...

An Evaluation of Low-Cost Vision Processors for Efficient Star Identification

open access: yesSensors, 2020
Star trackers are navigation sensors that are used for attitude determination of a satellite relative to certain stars. A star tracker is required to be accurate and also consume as little power as possible in order to be used in small satellites.

Non-Dimensional Star-Identification

open access: yesSensors, 2020
This study introduces a new “Non-Dimensional” star identification algorithm to reliably identify the stars observed by a wide field-of-view star tracker when the focal length and optical axis offset values are known with poor accuracy.

Algorithm with Patterned Singular Value Approach for Highly Reliable Autonomous Star Identification

open access: yesSensors, 2020
In the work reported in this paper, a lost-in-space star pattern identification algorithm for agile spacecraft was studied. Generally, the operation of a star tracker is known to exhibit serious degradation or even failure during fast attitude maneuvers.
