Subject: Submission of gscwd52 series to IDS Data Centers.



We have submitted a new SINEX series, gscwd52, to the
IDS Data Centers. This series is identical to gscwd50
(prior to the launch of Sentinel-3A), and identical to
gscwd51 between the launch Sentinel3A and Sentinel3B.

GSCWD52 includes Sentinel3B after 2018-06-06.

We note a similar POD performance for Sentinel-3B as for Sentinel-3A.
The SLR fits to slr+doris orbits are an average 0.791
cm over 197 arcs from June 2018 to July 2021, with
an average of 870 SLR observations and 75221=20
DORIS observations per arc.=20

As with the processing for the other DORIS satellites,
the elevation cutoff is 7 degrees for Sentinel3B, and
we apply an elevation dependent function.

For further information on the modeling with regard=20
to this series, we refer the readers to the description
file for this series at the IDS Data Centers, and/or
