GNSS Remote Sensing: Recent Results from GFZ

Kurzfassung

During the recent two decades ground and satellite based GNSS remote sensing (GNSS-RS) methods evolved into a versatile and powerful tool for Earth System Research on different spatiotemporal scales with operational applications. Large regional and global GNSS ground networks and 100+ space-borne receivers provide unique atmospheric/ionospheric data and observations of the Earth's surface. This receiver infrastructure will be further developed during the coming years and become the base for increased importance of GNSS-RS techniques for Earth Observation. One of the leading institutions for these developments is the German Research Centre for Geosciences GFZ at Potsdam. Beside various scientific activities to further develop and improve GNSS-RS techniques, GFZ also advances related, in part operational, applications for weather/climate and ionosphere research with cooperation partners. We briefly review recent developments in GNSS Remote Sensing at GFZ with focus on ground and satellite based atmosphere/ionosphere sounding and reflectometry.
