FIELD: the invention refers to the field of radiolocation and may be used in cellular communication systems for augmentation of accuracy of definition of the position of a mobile station. ^ SUBSTANCE: augmentation of accuracy of definition of the position of a mobile station is achieved due to forming of data base of multibeam mistakes of pseudo-distances in accordance with the terrain( open country, urban area, rural area etc.), an elevation angle of the satellite and the correlation signal-noise for the satellite received signal. The evaluation of the parameters of the multibeam mistakes with taking into consideration the type of the terrain, the elevation angle of the satellite and the correlation signal-noise allows the most effectively to take into account the propagation medium of the satellite's signals and obtain a statistic description of multibeam mistakes. The using of the elevation angle of the satellite and the correlation signal-noise allows to take into account not only the multibeam mistakes but also the noise mistakes at pseudo-distances measuring. ^ EFFECT: increasing accuracy of definition of the position of a mobile station. ^ 1 cl, 6 dwg
