Earth orientation parameters from the CONT17 campaign

In this work, we study the Earth Orientation Parameters (EOP) estimated from the continuous VLBI campaign CONT17. This campaign consisted of two station networks observing in parallel for 15 days, allowing for interesting comparison of the results. We find that the WRMS differences between the EOP estimated from the two networks are in the range 40–70 μas. Similar agreement is found with the polar motion estimated from GNSS. We also investigate the high frequency EOP variations and confirm earlier findings that the current IERS model for high frequency EOP variations needs to be updated.
