A robust star identification algorithm with star shortlisting [PDF]
Advances in Space Research, 2018 Abstract A star tracker provides the most accurate attitude solution in terms of arc seconds compared to the other existing attitude sensors. When no prior attitude information is available, it operates in “Lost-In-Space (LIS)” mode. Star pattern recognition, also known as star identification algorithm, forms the most crucial part of a star tracker ...

Blind Star Identification Algorithm
IEEE Transactions on Aerospace and Electronic Systems, 2020In this paper, a new algorithm called blind star identification is presented to identify the stars in night sky images without using the intrinsic parameters of the star sensor camera (focal length, principal point, and pixel size), and in lost in space mode.

Evaluation of Star Identification Techniques
Journal of Guidance, Control, and Dynamics, 1997Traditionally, star sensors have used fairly large e elds of view and bright stars to perform tracking and identie cation. Recent trends in space missions have brought out the need for smaller e eld-of-view sensors, capable of performing multiple functions that will reduce spacecraft payload and cost.

Improvement of star identification based on star trace in star images
Measurement: Journal of the International Measurement Confederation, 2017Abstract Digital zenith camera system is a highly accurate positioning instrument in geodetic astronomy. It can capture 16 star images in one experiment unit in different azimuthal camera orientations and the stars in each star image should be identified using star catalogue.

A fast recognition algorithm for star identification of star trackers
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017This paper focuses on recognizing the correct match of star identification among multiple possible candidates for star trackers. Derived from the perturbation theory, a tolerance criterion is proposed and proved to check the correctness of the candidates.

Stochastic star identification
Journal of Guidance, Control, and Dynamics, 1994Summary: An approach to star identification based on comparing observed pattern statistics with the precomputed star cataloged statistics is suggested. The identification criterion is based on evaluating a posteriori probabilities of designated star sequences obtained from observing different star fields. Numerical results based on a specific algorithm

Star-field identification algorithm
Optics Letters, 1993A six-feature, all-sky star-field identification algorithm has been developed. The minimum identifiable star pattern element consists of an oriented star triplet defined by three stars, their celestial coordinates, and their visual magnitudes.

IDENTIFICATION OF STARS BY LEARNERS
Empire Survey Review, 1960AbstractIt is not customary in text-books on surveying to treat the identification of stars as a subject requiring detailed discussion; nevertheless with learner-surveyors and occasional practitioners it is a major problem.

Nondimensional star identification for uncalibrated star cameras
The Journal of the Astronautical Sciences, 2006Star identification is the most critical and important process for attitude estimation, given data from any star sensor. The main purpose of the Star Identification (Star-ID) process is to identify the observed/measured stars with the corresponding cataloged stars.

An Analytical Approach to Star Identification Reliability
AIAA Guidance, Navigation and Control Conference and Exhibit, 2008Abstract The problem of real-time, on-board star pattern identification is considered which must precede any spacecraft attitude estimation algorithm based on measured line of sight directions to stars. Following the use of the search-less k -vector method to access feasible candidate stars (detailed in a previous paper) a tiered logical ...
