Pdf Dynamic Imaging Model And Parameter Optimization For A Star Tracker Pdf | under dynamic conditions, star spots move across the image plane of a star tracker and form a smeared star image. On the basis of the imaging model of ihdst and the monte carlo method, the influence of the star tracker working parameters, such as exposure time and gain control voltage, on the star locating accuracy is analyzed in this study.
Star Tracker Ideal Imaging Model Download Scientific Diagram A model is now available to represent the optical transfer function for a linear system that generated light by a single star and propagated it through the optical system of the star tracker, and imaged on the fpd with optical aberrations. The proposed model, which has a clear physical meaning, explicitly reflects the key parameters of the imaging process, including incident flux, exposure time, velocity of a star spot in an image plane, and gaussian radius. This paper focuses on how exposure time affects the star tracker under highly dynamic conditions and how to determine the most appropriate exposure time for this case. firstly, the effect of exposure time on star detection sensitivity is analyzed by establishing the dynamic star spot imaging model.

Abstract: under dynamic conditions, star spots move across the image plane of a star tracker and form a smeared star image. this smearing effect increases errors in star position. This paper focuses on the global field of view (gfov) imaging performance of a high dynamic star tracker (hdst) and a solution of gfov optimal parameters is presented for the best performance in centroid estimation.
