As one of the ten analysis centers of the International GNSS Service (IGS) we process thousands of GNSS observations each day to derive precise station coordinates, satellite orbits, satellite clock corrections and Earth rotation parameter. Our products ultra-rapid (latency 3-9h), rapid (latency (1 day) and final (latency two weeks) are currently available for GPS and GLONASS.
All processings are performed using the GFZ developed EPOS.P8 software which is in line with the current geodetic conventions. The high accuracy of our products is ensured by the comparisons and combinations done by the IGS Analysis Center Coordinator. From 2003 to 2007, this task was carried out by GFZ which provided the official combined satellite orbit and clock products.
