Abstract. The article aims to study the values of a geometrical factor of the global navigation satellite systems (GNSS) GLONASS, GPS and GALILEO in different latitudes in a certain longitude. The study was conducted with the help of special software developed by the authors and tested at S. M. Budjonny Military Academy of the Signal Corps. The geometrical factor is included in the structure of the errors of the navigation-temporal settings of radio-navigation systems. Predicted geometrical factor values allow evaluating the error of solving a navigation task under a certain mistake in radio-navigation parameters identification, in particular, at the preparatory stage of navigation equipment use by GNSS users.
