Efficient algorithms for calculating dark current in primary image processing in real time for typical modes of operation of a stellar sensor are discussed. We present a way to reduce the orientation error by improving the accuracy of the position of the photocenter of the star image on the radiation receiver, a charge-coupled matrix device. The dependence of the error in determining the photocenter coordinates on the standard deviation of the irregularity of the thermogeneration rate, expressed in units of the mean value, is shown. A part of the dark frame of the charge-coupled matrix device with distinct trap traces is considered. The emission trace of the trap, on which the signal from the "hot"element has hit, stands out especially brightly. © 2023 Author(s).
