Subject: USNO receiver replacement

On 26 October 1999, the USNO receiver at the U.S. Naval Observatory,
Washington, DC, USA was changed from an AOA ROGUE SNR-12 RM (s/n T246)
to a retrofitted AOA SNR-12 ACT (s/n 245-U).  USNO data reported to
the IGS for DOY 299 are for the TurboRogue receiver and cover up to
about 19:00 UCT.  Beginning with DOY 300,  USNO data will be using
the ACT receiver; the data download and RINEX translation procedures
for USNO will conform to the recommendations of IGS Mail 2320
(24 June 1999) for handling mixed receiver types.

An updated site log will be sent to the IGS Central Bureau today.
