Below is an announcement from Juan Palacio (Real Instituto y Observatorio
de la Armada, Spain) of a new permanent geodetic station ROAH collocated
at the ROA timing laboratory with the existing SFER station. The
differences between the two receivers and their relationship to UTC(ROA)
are explained below. Juan is preparing an IGS log file to submit to the
IGS Central Bureau, which will be available at
http://igscb.jpl.nasa.gov/igscb/station/log/ . --Jim

Dear colleagues:
This message is to communicate you that ROAH permanent station has
been succesfully installed and its data are daily collected and they are
now avilable to IGS community. Our collaboration is a result of the
IGS/BIPM Pilot Projet for Time and Frequency Comparisons using GPS.
I am also sending an application to IERS to request the DOMES number
for the station.
All the best,
Juan Palacio

Dear Jim:
Thank you very much for your comments.
Yes. I forgot to mention that SFER is collocated with the new station.
ROA decided to mantain the two station if they are not on the same network
( I mean the official IGS station is SFER and ROAH is only for IGS/BIPM
project collaboration).
TTR-4P is based on AOA Turbo-Rogue, it is a 8 channel geodetic receiver
with an external frequency reference input and an external 1PPS (UTC(ROA)).
TTR-4P can work in three diferents way: navigation, fixed and clock.( Mirhan
Miranian can give you, better than me, further details on each operation
mode). The difference with Trimble is that the later has no time reference
input, so its internal timing reference is driven by the frequency of one of
our cesium clock, but we do not know the diference between internal clock
and UTC(ROA).
Please find attached a sample of the RINEX obs. file coming from TTR-4P.
Thank you again for your comments. I have read again the station log
with more attention and I have found some other errors I am going to
rectify.
Best regards,
Juan Palacio
