description: The object of study is a simulator of GNSS GPS signals The purpose of the work is to study the dependence of positioning accuracy on the relative position of the satellites and the receiver In this work, using the GNSS GPS simulator model, the influence of the relative position of the satellites and the receiver on the positioning accuracy of the receiver of satellite navigation systems has been studied. The simulator model, developed in the MATLAB environment, carried out such basic stages of processing the navigation message as the detection and tracking of satellites, as well as the calculation of the coordinates of the receiver. Intermediate steps such as signal generation and propagation have also been simulated. As a result of the study, correctly working detection, tracking and positioning algorithms have been obtained. The results of the study of the dependence of the positioning accuracy on the location of the satellites and the receiver in relation to each other correspond to the theory. Open educational resources and programs for searching and analyzing information were used. MATLAB automated development tool was used. Software WORD and POWER POINT were applied.
