Analyses of GLONASS and GPS+GLONASS Precise Positioning Performance in Different Latitude Regions
Remote Sensing, 2022 The orbital inclination angle of the GLONASS constellation is about 10° larger than that of GPS, Galileo, and BDS. Theoretically, the higher orbital inclination angle could provide better observation geometry in high latitude regions.
