Dear IGS DC colleagues,
As you can see from the email below, the IGS is hoping to start
accepting data in RINEX version 2.11 format, with the new observables,
into the operational data flow. Can each data center contact please
respond to this email with your opinion as to when you will be ready
to accept the new version into your operations, thus providing the data
in the "normal" data stream? We would like to try to get the new
format into operations by the end of 2006.
Thank you,
Carey.

> - Decision to accept or skip new GPS observables (L5, wich

> - Decision to accept or skip Galileo observables (which currently

> - Decision to accept or reject GAL time system

> These are minor changes which can be introduced in the processing
