[EUREFmail-09748] - 2019-02-18 (27/02/2019)

We are glad to announce that from February 17, 2019 on, one new
permanent GNSS station will be included in the EUREF Permanent
Network : the station TLL100IRL (Dublin) in Ireland, which is operated
by the Ordnance Survey Ireland (see

Type antenna calibration values for that station (LEIAR10/NONE)
are included in ftp://epncb.eu/pub/station/general/epn_14.atx.

The complete station log can be retrieved from the EUREF permanent
network Central Bureau : ftp://epncb.eu/pub/station/log or
through the web-page of the station :

The Ocean Loading tables
ftp://epncb.eu/pub/station/general/EPN_FES2004.BLQ and
have been updated in order to include that station.

The daily and hourly RINEX 2 (GPS/GLO) data are available from the
BKG and BEV EPN regional data centres.

The data of TLL100IRL are processed by the IGE, ROB and WUT
analysis centres.

We expect to see the results in the EUREF combined solution from
GPS WK 2041 on.
