Author:  Carey Noll/CDDIS

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.

> Dear colleagues,
>
> at last week's meeting of the EUREF Technical Working Group it was  
> discussed how
> to handle/distribute/archive data from receivers generating L2C  
> observables and
> stored in RINEX 2.11. The current solution adopted by IGS to store  
> such data in
> separate directories was questioned and judged not to be adequate  
> anymore. After
> more than one year of data available in 2.11 and with an increasing  
> number of
> L2C-capable receivers (and soon satellites) we feel it's time to  
> accept such
> data files in the official and routine data flow of IGS.
>
> The modifications of processing software to accept RINEX 2.11 are  
> minimal:
>
> - Accept the new version number
> - New observation code for L2C with the decision to accept or skip  
> these
> observables
> - Decision to accept or skip new GPS observables (L5, wich  
> currently don't exist
> anyway)
> - Decision to accept or skip Galileo observables (which currently  
> don't exist in
> the IGS data flow anyway)
> - Decision to accept or reject GAL time system
>
> These are minor changes which can be introduced in the processing  
> software
> rather quickly. The acceptance of 2.11 will simplify the data flow  
> and in fact
> give the stations with the new receivers the visibility they  
> deserve without
> having to support two separate data chains.
>
> We urge you to introduce these modifications as soon as possible,  
> after an
> appropriate lead time, of course.
