A Study on the Performance of RTK Positioning by GPS and GLONASS

Abstract

GLONASS is a global positioning system launched and operated by Russia. The effect of the improvement of shortening the initialization time of RTK and the improvement of the measurable range by using GPS together with GLONASS are expected because there are a lot of numbers of usable satellites by GLONASS. In this research, the authors executed basic experiment on the effect of using with GPS together of the GLONASS. As a result, it was confirmed that the initialization time shortened 10 seconds on the average besides the FIX accurate measurement rate improved by 30% at a maximum.
