Research on GPS/GLONASS/GALILEO Multi-constellation Integrated Navigation System

Abstract

Abstract: The position algorithm of multi-constellation integrated navigation system was researched.Due to the different reference coordinate and time systems used in GPS,GLONASS and GALILEO system,coordinate conversion and increased elements method were adopted to realize the space-time unification.Aiming at the increasing number of visible satellite,the least square method was used in the position calculation to improve the precision.Simulation validation was carried out on GPS,GLONASS and GALILEO multi-constellation integrated navigation system and the results indicate that in contrast with the GPS single system,the GPS/GLONASS/GALILEO multiconstellation integrated navigation system has perfect orientation ability and reliability,and can simultaneously gain more visible satellites,diminish PDOP value and improve the position precision effectively.

Key words: Multi-constellation, Space-time unification, Navigation, Positioning, Satellite
