Dear Colleagues,

There is a new IGS station today: USN3

USN3 is located at the U.S. Naval Observatory in Washington, D.C.,
USA.  It replaces the IGS site USN1 and is connected to the
reference signal from the USNO Master clock MC2, the primary
realization of UTC(USNO), with all calibration values already applied
to the raw data.  A new antenna, new position of the antenna,
and higher-stability signal splitter are expected to increase
the data quality.  Data delivery is hourly (and 15min/1Hz).  USNO
operates the station, with JPL supporting the data flow and site log
generation.

The site log is installed at the CB, and you will begin to see USN3
appear in the various station lists and maps.

Best regards,
Angie
