To determine the zenith tropospheric delay in GPS measurements

Department «Higher geodesy and astronomy» of Lviv Polytechnic National University

The analysis of the determination of both dry (hydrostatic) and wet (nonhydrostatic) components of zenith tropospheric delay is performed on the ground of aerological sounding data in three major regions of Antarctica and in South-West part of Ukraine. These components were determined and estimated for some known analytical models as well. The recomendations regarding futher development of such investigations are made.
