The detailed adaptive unscented Kalman filter algorithm is provided.Step-by-step schemes of filtering algorithms used for the software development are given.Nonlinear filtering algorithm efficiency is investigated with considering an example of a nonlinear continuous-discrete model.The statistic estimator based on the continuous-discrete adaptive unscented Kalman filter with noise is proposed for the nonlinear system parameters estimation.The solution to the problem of solar radiation parameters estimation based on the maximum likelihood method and the adaptive unscented Kalman filter is shown.The obtained results lead to significant improvement of satellite trajectory prediction quality.
