description: This work is devoted to the study of filters of tracking lock loops for the code and carrier in the receiver of signals of satellite navigation systems with different dynamics of the satellite-receiver system. In the MATLAB environment, a model was developed for simulating the correlator operation with reference signals. Also proposed are the dependences of acceleration on time, which describe several models of the dynamics of the GNSS signal receiver. Using the simulator model, the filter parameters are obtained: the order and the band, at which the tracking systems with a given dynamics have the best stability in conditions of low SNR. With the help of theoretical formulas describing the sources of errors of the tracked parameter, theoretical curves were obtained that describe the dependence of the dynamics (acceleration and jerk of the satellite-receiver system) on the filter bandwidth. As a result of modeling the tracking lock loops, the dependences of the standard deviation of the error in the estimation of the tracking system parameter on the SNR were obtained and the filter parameters were determined, which make it possible to achieve the greatest filter stability.
