POSE ESTIMATION OF A MOVING CAMERA WITH LOW-COST, MULTI-GNSS DEVICES

Tropospheric delay comprises one of the most important error sources in satellite navigation and is caused when radio signals broadcasted by GPS satellites propagate into the atmosphere. This study aims to evaluate the tropospheric delay performance for GNSS integrated water vapor (IWV) estimation by using GPT2w model, ECMWF's IFS reanalysis model and ground meteorological data from two stations of the permanent network of Cyprus and Greece.
