description: The given work is devoted to assessment of the decrease in the accuracy of determining the coordinates of a ground source of radio emission due to the geometric factor. A model of a three-channel geolocation system using the TDOA-TDOA method has been developed. The dependences of the magnitude of the error in determining the coordinates of the radio emission source on its location relative to the relay satellites, as well as on the choice of relay satellites in the geostationary orbit, are obtained. An ellipse of errors has been constructed, which makes it possible to estimate the error in determining the location of the desired source. From the obtained dependences, it is possible to draw a conclusion about the nature of the dependences of the error on the location of the radio emission source. The results also allow the selection of "adjacent" satellites-repeaters, in which the geometric factor will introduce a smaller error in the determination of coordinates.
