GNSS Infrastructure and Analysis

Observation data and derived products for the global navigation satellite systems (GNSS) provided by us serve as input for thousands of users worldwide in the field of Earth monitoring, navigation, timing, and various scientific and applications. We contribute by our activities significantly to the International GNSS Service (IGS) of the International Association of Geodesy (IAG).

Since the 1990s, we operate a global GNSS station network and develops GNSS hardware to support scientific research activities as well as operational services. Based on operational processing we provide highly accurate GNSS satellite orbit and clock products and support Galileo as a geodetic service provider since 2009. Within research projects, we develop improved clock modeling and optimal strategies to combine orbit and clock products. We are working on geodynamic topics and support different GFZ observatories and the ERC project TECTOVISION.

Our gfzrnx software is used worldwide to convert GNSS observations.
