Dear Jon,

 

Is it possible to accommodate some time in the agenda also for DLR in the presentation of optical activities by agencies? This would be in addition to the already planned contribution to the atmospheric characterization topic.

 

Thank you and kind regards,

 

Gianluca

I sent out Teams invitations for the face-to-face meetings. The meetings will start at 8:45am on Tuesday and Wednesday.

For the face-to-face meting I request that each agency come prepared to state their position on the proposal for a tighter phase noise mask than the OpenZR+ mask. That is, which of the three masks shown shown in Lucien's presentation at today's meeting would you like to see adopted into the CCSDS standard? Lucien said he would place his presentation in today's CWE meeting folder, at https://spacecomm.sharepoint.com/sites/SLS/Shared%20Documents/Forms/AllItems.aspx?id=%2Fsites%2FSLS%2FShared%20Documents%2FSLS%2DOPT%2FCWE%20Private%2FMonthly%20Telecons%2F2026%2F2026%2D09%2D24%20monthly%20meeting <https://spacecomm.sharepoint.com/sites/SLS/Shared%20Documents/Forms/AllItems.aspx?id=%2Fsites%2FSLS%2FShared%20Documents%2FSLS%2DOPT%2FCWE%20Private%2FMonthly%20Telecons%2F2026%2F2026%2D09%2D24%20monthly%20meeting&viewid=2be46707%2D54b3%2D4558%2Db9b5%2D1a581fddd2f7&FolderCTID=0x01200016AEFAC54964424C9CD979137E2A1E8A&View=%7B2BE46707%2D54B3%2D4558%2DB9B5%2D1A581FDDD2F7%7D> &viewid=2be46707%2D54b3%2D4558%2Db9b5%2D1a581fddd2f7&FolderCTID=0x01200016AEFAC54964424C9CD979137E2A1E8A&View=%7B2BE46707%2D54B3%2D4558%2DB9B5%2D1A581FDDD2F7%7D

Hello,
We have the same request from CNES concerning a slot in ? Presentations of optical activities by agencies?
We will also provide some inputs in ?Atmospheric characterization?
Is it possible to update the agenda please.
Thank you,
Cheers,
G?raldine

Yes, of course. I will update the agenda to include the DLR and CNES 
presentations on atmospheric characterization and on agency optical 
activities.
