Dlouhodobé porovnání kvality výsledků techniky dvojitých diferencí a techniky PPP pro účely GPS meteorologie

Abstract

Thesis deals with long-term comparison of results from PPP technique and double-differencing technique for the purposes of GPS meteorology. Introductory part of the thesis deals with GPS meteorology, namely with describing the atmospheric influences on the GNSS signal propagation. The thesis also contains a description of data processing using Precise Point Positioning method. In the final part a statistical evaluation of the results in the form of ZTD values from both techniques is presented. This comparison was carried out for 5 GNSS reference stations and about 400 days of data.
