• The setup of satellite-, plane-, or GNSS-specific ERP- and/orGCC-parameters was implemented.

• It is enabled for internal purposes in the operational solution sinceMay 2015 and the most recent reprocessing (see Poster by Susniket al.).

• The results from a GNSS-specific setup on the NEQ-level areequivalent to independent GNSS-specific solutions.

• There is almost no contribution from GLONASS to a combinedGPS+GLONASS GCC series (Z-component).

• Meindl et al (2013): due to the inclination of GLONASS satellites(64◦) the Sun may be almost perpendicular above the orbitalplane, which results in a direct correlation with dynamic orbitparameters.

• The GLONASS contribution to the ERPs is mainly limited by thethree-plane constellation.

• The ERP results from the GLONASS constellation are comparableto solutions with a synthetic three-plane GPS constellation.

• The geometric effect changes in time due to the regression of thenodes of the satellite’s orbital planes.

• The GLONASS contribution to the ERPs is mainly limited by thethree-plane constellation.

• Similar limitations may be expected for Galileo and theMEO-constellation of BeiDou.

• With a full multi-GNSS analysis the constellation effect shouldbeheavily reduced, ideally eliminated.
