Keywords: global satellite navigation systems tropospheric delay vertical profiles of troposphere

Abstract

The paper is focused on comparison of results of estimation of the GNSS troposphere delay. The four techniques were discussed: the delay according to the International Service of Gobal Navigation Satellite Systems (IGS); the delay which was found using vertical profiles of the atmosphere from satellite data; the delay based on the models of Hopfield and Saastamoinen. It was found that the satellite profiles of the atmosphere provide the most prompt and accurate estimation of tropospheric delay of GNSS signals.
