description: The given work is devoted factors reducing the accuracy of geolocation using the TDOA-FDOA method. A model has been developed that allows estimating the error in determining the coordinates of the radio emission source caused by the error in determining the information parameters, the geometric factor and the inaccuracy in determining the speed of relay satellites. Graphs of the dependence of the error in determining the coordinates from the above reasons were obtained using models of the trajectories of real satellites. The presented work increases the applicability of the TDOA-FDOA method, makes it possible to develop requirements for the accuracy of estimating the RMS of determining the speed of satellites to ensure the required positioning accuracy, and also to make recommendations for choosing the geolocation time for specific real satellites in order to reduce the error in determining the coordinates of the desired source of radio emission. The terminological features of the subject area are taken into account and software tools are used to solve problems. Specialized software and mathematical software were used: a package of applied programs for solving problems of technical calculations MatLab.
