description: The object of the study is a GNSS GPS signal simulator. The purpose of the work is to study the dependence of the positioning accuracy on the parameters of the time synchronization tracking loop. In this paper, the influence of bandpass filters of the tracking system on the positioning accuracy of the receiver of satellite navigation systems was studied. Using the MATLAB environment, a model of a GPS signal GNSS simulator was created, which allowed simulating the formation, propagation and processing of GPS signals up to the calculation of coordinates. In the course of the work, algorithms for detecting and tracking signals were developed, which demonstrated correct operation. Also, within the framework of the study, the filter parameters were obtained: the order and the band at which the tracking systems at a given dynamics have the best stability in conditions of low SNR. Distance errors were compared in various scenarios of user behavior simulation, and conclusions were drawn on how to reduce them. Open educational resources and information search and analysis programs were used. The MATLAB automated development tool was used. WORD and POWER POINT software are used. Thus, the result of the work is a simulator that allows you to quickly check the operation of the navigation signal processing algorithm and the accuracy of determining the coordinates of the receiver.
