[IGS-DCWG-201] on Rines 3/2 dual stations ... revised

[Nacho Romero]

Dear IC & DC,

After the last few days I think we can all agree that having stations 
switch too fast away from Rinex 2 would not be positive for the IGS+ 
community. Thus please comment on the following message we aim to send 
to the IGSSTATION/IGSMAIl/IGS-AC email lists (minimum)

The idea with the message is to cover these two ideas; to request 
station operators NOT to turn off their dual Rinex 2 files yet, to wait 
until the end of 2019 or as long as late as possible during this year, 
plus also to request that Rinex 2 files continue to be generated from 
raw receiver files (and not converted) .

Additionally Data Centers should institute checks to ensure the Rinex 2 
files conforms to the Rinex2.11 standard so that some of the recent 
problems (use of C3/L3 observations, inclusion of C7/L7 in Glonass, 
inclusion of Beidou and QZSS) are flagged and the files quarantined and 
the operators notified.

"Dear IGS members,

 From the IGS NC and IC we acknowledge that many stakeholders and users 
in the IGS+ community have adapted their tools to process station Rinex 
3 data files preferentially. This is as was intended in the Rinex 3 
transition plan as part of the move of the IGS to a truly multiGNSS 
service. On the other hand we have to recognize that Rinex 2 files 
remain important and some users have expressed concern at the 
disappearance of Rinex 2 from important historical stations.

As a data provider could you please continue submitting dual Rinex 
3/Rinex2 data files, if this has been your practice in the recent past, 
for as long as possible or until the end of 2019. The choice to continue 
to submit dual Rinex files is up to each station data provider but we 
request that you are sensitive to the IGS community since some 
components have not completed the transition to dual Rinex3/Rinex2 
processing yet. Thanks.

We would like from the IGS to also ask that Rinex 3 and Rinex 2 files 
are created from the receiver raw tracking files and not converted 
between them. Thanks.

Sincerely,

  Infrastructure Committee

  Network Coordinator
