This research focuses on one of the components in a satellite or spacecraft, namely the ADCS
(attitude determination and control system), especially the star sensor. The star sensor is one
of the attitude sensor for a spacecraft that works by utilizing the position of stars visually in a
certain field of view (FOV), taking into account various influential variables, such as star
brightness, camera quality, star catalog, and the algorithm used. The algorithm in question is a
star centroiding algorithm, a stage in star pattern recognition that detects star images and
calculates the position of each star in the FOV. This study aims to implement two existing star
centroiding methods, namely the center of gravity method and the center of gravity weighting
method, into a program, using the C++ language. The performance of the applied algorithm
will be tested with two characteristics, namely accuracy and processing time through digital
simulation. The digital simulation results show that the algorithm that has been applied shows
high accuracy for both methods, with an average error of 0.0463% and 0.0467% for the center
of gravity and center of gravity weighting methods, respectively, from a number of simulations
of 1500. The simulation also shows an average processing time of 19.9 ms and 20.4 ms for
both methods, respectively. |
