FIELD: radio engineering, communication.SUBSTANCE: method involves receiving signals for each satellite, taking code and phase undifferentiated measurements (10), determining broadband uncertainties in a coherent manner for all satellites (11, 12, 13) using broadband shifts associated with satellites and obtained from a reference system, and determining the geographical position of a receiver using code and phase measurements and matched broadband uncertainties (16, 18). Determination of the geographical position involves determining (16) pseudo-distance through a non-ionosphere combination of code measurements and the difference between phase measurements with compensated broadband uncertainty, wherein the combination is noise-optimised. In order to determine pseudo-distance, satellite clock signal values associated with the non-ionosphere combination are obtained from the reference system.EFFECT: high accuracy of position finding solution.11 cl, 3 tbl, 3 ex |
