GNSS Analysis Centres and Services

This research area includes activities within the IGS (International GNSS Service), development and improvement of GNSS data analysis software and contributions to the European Global Navigation Satellite System Galileo.

GFZ has been developing its GNSS analysis software EPOS for decades and is maintaining the software according to the latest standards and developments. GFZ is also very active in developing new algorithms in order to improve the quality of the IGS products and to enhance the capability of GNSS data processing.

Since 2007, GFZ has been developing its GNSS real-time software package, EPOS-RT. The software is designed not only to run in network mode which is now used for geohazard monitoring (earthquake, tsunami, volcano, landslide), but also to be able to estimate orbit and clock corrections to provide services to users with single-frequency receivers in precise point positioning mode (IGS Real-Time Pilot Project). The above-mentioned functions can be demonstrated now and further improvement on the robustness and accuracy of the software is in progress.

The Galileo Geodetic Service Provider (GGSP) was developed until 2009 with the target to support the In-Orbit-Validation for the Galileo System starting in 2011. This service will be offered to be part of the final Galileo system.

GFZ is operating a global GNSS station network (currently ~30 stations) since the early 1990s to support scientific research activities like precise satellite clock & orbit determination, radio occultation measurements and crustal dynamics. Additionally operational services for the European satellite system Galileo and various scientific campaigns are supported.
