Datasets of the full GNNS site (GPS, Glonass, Galileo) are transmitted continuously to GFZ in Potsdam in real time, where they are evaluated for two purposes. Firstly to determine station coordinates, ephemerides for all GNSS-satellites and high temporal resolved vertical integrated water vapor profiles for the International GNSS Service (IGS). Secondly they are used as reference for satellites with special on board GNSS receivers to
determine their exact orbit and to calculate water vapor profiles (GNSS radio occultation method). The GNSS receiver is also integrated into the GRUAN project.
The system is operated continuously through the year (24h/7d operation) with remote control
from GFZ in Potsdam.
