Highly-Precise Point Positioning by Signals from Global Navigation Satellite Systems Using Refined Ephemerid-Time Data

Aspects of updating the method for highly-precise point positioning by signals from global navigation satellite systems are considered. The method uses the refined ephemeris-time data that are created by augmentations of global navigation satellite systems. The algorithm of determination of user's coordinates is proposed and results of experimental studies are given on basis of which conclusions are drawn regarding the prospects of developing the systems of augmentations for global navigation satellite systems.
