Image-Driven Hybrid Model for Sun Sensor Attitude Determination

Abstract

AbstractCurrent calibration methods for digital sun sensors typically use the spot center as input. These methods establish a physical model that relates the spot center to the incident angle of sunlight for attitude estimation. However, defects in the ...Practical ApplicationsSun sensors face two major challenges during attitude determination: inaccurate localization of irregular spots and inadequate compensation for nonlinear and unknown errors. To solve these problems, this paper proposes a hybrid model ...
