[SLS-CC] Concept paper for WG comments (deadline: 18 June 2019)

[Massimo.Bertinelli at esa.int]

Dear all,

following the deadline, I've received comments only from DLR (email from 
Tomaso de Cola, 06 June), that I copied herein for your convenience:

###############################################################################################################################################
Dear Massimo,
 
Just few comments from my side:
 
·I understand the project is about the extension of the present 131.3-B-1 
to allow interworking of DVB-S2 with USLP and AOS. However, the 
description refers only to USLP. Similarly, the description provided in 
Annex 2 points only to USLP and generically about space-to-space and 
ground-to-space links. I’d suggest to explicitly mention AOS too.
· In general from the purpose and the description of the project, it is 
not fully clear to me which technical work is planned here. Is it just 
about adding a chapter about specifying the codes (as I read from the 
description)? As such I understand, that new codes other than those of the 
ETSI DVB-S2 specification will be considered in this new chapter. Then, I 
also read that this new chapter will also specify the space link 
protocols. What does it mean exactly? Apparently I see something more than 
just “editing work”, probably requiring validation through 
interoperability testing (i.e. with the typical 2 prototypes). Why isn’t 
it the case?
· In the section dedicated to the schedule, I read October 2019-October 
2020, i.e. 12 months. However, immediately below it is stated “time to 
complete 17 months”.
 
Thank you in advance for the clarifications/comments to my doubts.
 
Best Regards,
Tomaso

Dear colleagues, 

please find a concept paper provided by CNES, for the extension of CCSDS 
131.3-B-1 to ground-space and space-space links, and for the use of USLP. 
Your comments, if any, are expected by 18 June (2 weeks), before I proceed 
with requesting the resolution for the project approval. 

Best regards, 
Massimo
