ABOUT THE IMPACT OF COMMUNICATION CHANNEL ON GNSS RADIOSIGNALS PROPAGATION IN THE KHARKIV REGION

Abstract

In the paper we presented the results of systematic measurements of the positioning precision of several stationary navigation stations with known coordinates, which are equipped with single- and dual-frequency GPS/GLONASS navigation receivers. Particular attention has been paid to environment parameters caused by rains (including summer rains with thunderstorms), snowfalls, fogs and clouds. The experimental investigations of the fluctuations of zenith tropospheric delay and spatial coordinates of the reception stations located at the distance of 5.8 km have been performed. The factors which limit the maximum permissible positioning precision have been evaluated. The results of the paper are relevant to the problems of operative prediction of the meteorological phenomena and researching their physical properties.
