METHOD OF DETERMINING POSITION OF NAVIGATION INFORMATION USER OBJECTS AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC G01S5/14 

FIELD: physics.

SUBSTANCE: in a method of determining the position of a user object from navigation radio signals, where navigation parametres are determined - measurement of pseudorange and phase of the signal at pseudo-Doppler frequency from navigation radio signals of an orbital group of navigation spacecraft NKA1 of the GLONASS system and NKA2 of the GPS system, the user is sent basic navigation information and auxiliary information from which the position of the object is determined. Navigation radio signals are used in three frequency ranges L1, L2 and L3 for the GLONASS system and L5 for the GPS system respectively. Auxiliary information is supplemented with data on the state of the troposphere and parametres related to movement of the Earth in the solar system. Basic navigation information is generated onboard navigation spacecraft NKA1 using a network of ground-based base stations and a system of intersatellite communication and measurements.

EFFECT: more accurate determination of the position of a user object working in absolute mode to a level achieved using differential navigation systems.
