Abstract Advanced remote sensing tools based on space geodetic techniques are widely used for variouspurposes, such as monitoring sea level, snow depth and, in particular, sounding water vapor which isthe most abundant and important greenhouse gas in the Earth’s atmosphere. Over the past decade,GNSS Meteorology technique have become an effective tool for obtaining tropospheric parametersof the atmosphere. Moreover, GNSS reflectometer technique has been used in the last few years forobtaining important physical parameters such as snow depth and water level change with hightemporal resolution and high accuracy. The main purpose of the study is monitoring the HorseshoeIsland region's tropospheric water vapor variations, snow depth and ice thickness changes by meansof GNSS Meteorology and GNSS Reflectometry techniques. For this purpose, determination of tidaleffect and monitoring of snow / ice heights on Horseshoe Island will be carried out with observationsof ultrasonic level sensors, meteorological stations and GNSS stations specially designed for thesubject. In this respect, the Troposphere and Sea Level Reflectometer Observation Station and theTroposphere and Snow / Ice level Reflectometer Observation Station have been developed inaccordance with the challenging weather conditions of Antarctica region with the cooperation ofYildiz Technical University and Istanbul Technical University. These comprehensive observationstations are based on space-based geodetic systems and are designed to produce output bycombining high accuracy sound wave positioning data and meteorological station data. In addition,the parameters obtained from these stations will provide important information to support otherscientific studies such as bathymetric mapping, geological and geophysical studies, real-timepositioning, navigation and tectonics. We believe that the observations of these stations willcontribute to the monitoring of global climate change and will support the scientific studies of ourcountry in Antarctica. Keywords: GNSS ...
