FIELD: radio engineering.
SUBSTANCE: hybrid combination of data on orbit of satellites is used in method and system of mobile station. In one aspect, the mobile station combines the predicted data on orbit from one satellite and real-time data on orbit from the other satellite at determination of fixation; at that, combination can be provided for satellites in similar or different satellite systems. Mobile station can apply the real-time data on satellite orbit during one period of time and predicted data on orbit of the same satellite during the other period of time. In the other aspect, the mobile station can apply the real-time data on orbit for correction of time shift in the predicted orbit data. Correction of time shift can be made for the same satellite which provides the real-time data on orbit or for the other satellite in the same or some other satellite system.
EFFECT: possibility of allowing the receiver of satellite positioning system to use the available orbit data for output of accurate positions and synchronisation, even when current real-time information on orbit and time shift is not available.
