[Cesg-all] Re: Date / Agenda for the D-DOR meeting at next CCSDS Workshop in Rome

[Peter Shames]

Nestor,

This sounds like a good discussion.  The one additional element that  
needs to be considered is how we actually deliver the data (Nav WG  
product).  We are assuming that radiometric and ranging data will be  
returned using the CSS CSTS service.   Of course, if any of these  
results are just files then FTP can be directly used.   However, for  
some of these data types they will be stream data and an SLE style  
service then seems more appropriate.

Several of us will be meeting here at JPL prior to this proposed  
telecon to discuss the end to end and process flow issues.  The  
results of that meeting will be available for discussion.

Regards, Peter
