[SLS-CC] [EXTERNAL] reminder AI VLFs

Mon Sep 12 07:43:51 UTC 2022

Dear colleagues,
 with reference to my last email below, I received an additional input 
from ESA (Felix Flentge), about the use of VLFs with LTPv2.

I hope it will help for the concept paper, for finally formalising the VLF 
project.

However, I still invite all CCSDS member agencies to provide user cases by 
Fall meeting, in view of the AI that we defined last meeting.
The more the user cases, the better we can justify the introduction of 
VLFs.

Subject: [EXTERNAL] [SLS-CC] reminder AI VLFs

Dear C&S WG, 
 concerning the AI on VLFs, I received just a single input from ESA as in 
attachment.
It refers to Earth Observation and SCI missions using RF links only: it is 
shown that VLFs advantages are quite low.
Before closing the AI, given the vacation period, could you let me know by 
9th September if your agency plans to submit any input for the action item 
in subject, and when?
As discussed during Spring 2022, it would be useful to have such inputs 
well before Fall meeting 2022, for finalising the concept paper.
Otherwise, in absence of use cases, I see difficult to proceed in having a 
project for VLFs.
@Bern, Greg: if you could pool your WGs as well.
Andrea

Dear all, 
for the C&S Spring MoM 2022, I have just received a few comments that I 
have implemented. 

You can find in attachment the final PDF file, that I will upload on CWE, 
and, for your convenience, the .doc file with the track changes. 

Finally, I reminder that the first AIs (use cases for VLFs) is due by July 
2022, so please send your inputs (with CC Bern, Greg, and Ken) no later 
than 27th July 2022. 

Kind Regards

Subject:        [SLS-CC] Spring 2022 - MoM and input for SLS to CESG 

Dear colleagues, 
you can find in attachment the draft MoM of the C&S WG meetings, including 
the joint meetings with SLP, RFM, and OPT. 
In attachment there is also a powerpoint of the input that I would like to 
send to SLS AD for the CESG meeting about having an OpenISL project. 

Could you send me your comments no later than 24th EOB? 

For Bern, Dennis, and Greg, can you pool your WG as well for comments? The 
relevant content for your WGs is as follows: 
RFM: Section 3 of MoM + AI list + Powerpoint 
OPT: Section 1 of MoM  + AI list 
SLP: Section 1, 2 and 3 of MoM + AI list + Powerpoint 

Regards
