Alternative navigation systems use for satellite positioning in Russia

Abstract

The article provides a comparative analysis of the joint application and accuracy of determining the locations by GLONASS, Galileo, BeiDou satellites, obtained from the navigation messages and available forecasting algorithms. Nowadays the high-precision satellite definitions are based not only on the two-frequency measurement mode use, but also on the information inclusion from various existing satellite systems in processing [1,2]. Practical experiments performed in 2016 at latitude B=47° and presented in [3], confirmed the advantages of the GPS and GLONASS satellite systems’ joint use. To date, alternative GNSSs have appeared - the European “Galileo” and the Chinese “BeiDou”, the capabilities’ studies of which are not given due attention to. Therefore, we will try to compare the location determination accuracy by GLONASS, Galileo, BeiDou satellites received by the navigation messages, by comparing them with the exact data provided by the International GNSS Service (IGS), as well as with the available GNSS prediction algorithms available on the satellite observation equipment manufacturer Trimble site.
