[Sls-rfm] Fw: Orange Book DVB-S2x, updated concept paper - ESA comments

[Enrico.Vassallo at esa.int]

Dear Massimo,

I would like to submit the following comment as ESA.

As expressed during the presentation of the concept paper in the Hague, 
ESA is concerned that CCSDS approval of such OB for use in the EESS X-band 
may cause RFI beyond what computed in SFCG and which resulted in an SFCG 
and an ITU-R recommendation on power flux density limits.
The most logical solution would be to add the SFCG review cycle in the OB 
loop. ESA understands that this may cause the schedule to expand beyond 
the proponents' wishes.
As compromise, ESA proposes to remove the indication of the bands by 
simply deleting the sentence

 "DVB-S2X can be used for both X and Ka-bands." 

ESA understands that removing this sentence from the concept paper does 
not prevent the bands from appearing somewhere else but is ready to run 
the risk and approach the issue again as needed.

Please feel free to submit this also to the C&S list.

Best Regards,

E. Vassallo

Dear WG members,

as agreed during the &CS/RFM meeting in Den Haag, CNES and Jaxa will 
prepare an Orange Book for DVB-S2x.
CNES provided an updated concept paper for the work to be done, attached.
Could I please have your comments, if any, by the end of next week (Fri 22 
December)?
I realise the time is short (with the Xmas period coming), but the work 
has been already agreed upon during the Den Haag meeting,
so I'm just asking your comments to the concept paper.

I trust that Enrico will do the same for the RFM WG.

Best regards,
Massimo
