Abstract

In this article presents a methodology for choosing the best configuration of ground base stations of a local navigation system. Local navigation systems are actively used for navigation and time support of ground and air objects, the accuracy of determining the coordinates of which depends on the magnitude of the geometric factor – a measure of the deterioration of accuracy in the navigation receiver. The relative location of ground base stations directly affects the value of the geometric factor, and, consequently, the accuracy of determining the coordinates in the navigation equipment of consumers. However, it should be taken into account that the choice of the relative location (configuration) of ground base stations is influenced by the energy availability of signals from ground base stations in the navigation zone, the terrain features on the routes “ground base station – navigation equipment of consumers “, the required size of the area of operation of the local navigation system, the size of the zone in which it is possible to place a ground base station, the presence of direct radio visibility from the ground base station to the navigation equipment of the carriers, attenuation of the signals of the local positioning system on the route of propagation of radio waves “ground base station – navigation equipment of consumers”. This technique takes into account the above limitations and suggests using the arithmetic mean of the geometric factor in the navigation zone as an indicator of efficiency
