[CMC Alert] RE: Urgent Action Items from the Fall 2014 London Meeting

Fri Jan 23 16:59:55 UTC 2015

Bonjour

On the action CMC-A-2014-11-09, I confirm the big interest of CNES and our proposal to take editorial responsibility to produce the Planetary Communication Green Book.

CNES believes it is appropriate to define now the roadmap on how to harmonize practices and solutions for the communications in the various domains of Mars, Moon, Planets or Asteroids.

We believe this is the objective of the GB document as it is defined:
"The Green Book will include the following items:
1) Identification of the functional and performance requirements for a CCSDS planetary communications standard in line with systems requirements and in coordination with SFCG. The SFCG recommendation allocating frequency bands for each identified type of link needs to be analyzed by CCSDS to assess how it fits technically from a CCSDS viewpoint. For instance, in the PCOM SIG, proposals were made for links at 5 GHz and in optics, two bands which are not in the SFCG rec. Aspects like feasibility of data rates, Tx power, antennas vs frequency bands, positioning issues, ... will be addressed.
2) Collection of the various mission profiles corresponding to the identified missions scenarios as well as system requirements along the lines of agencies' mission needs.
3) Revision of the state-of-the-art system architectures, techniques and technologies susceptible to be adopted in a future planetary communications standard"

The objective is not to replace whatever exists in CCSDS now but to perform an overview of the requirements and the inventory of the most appropriate technologies to support them.
No Blue Book is planned at this stage.
If no work is advanced on these subjects now, as they refer to the underlying technologies, is it worth advancing on higher layer ones, like DTN, Messaging or Applications ... as they may not be cross supported in the context of the actual missions ?

For the CMC consideration.

Objet : [CMC Alert] Urgent Action Items from the Fall 2014 London Meeting
Importance : Haute

Dear CMC Members:

Below are three of the most urgent action items assigned to the CMC from the recent meeting in London. Nestor's chart for Action Item CMC-A-2014-11-03 is attached. The changes to the Procedures and Publications Manuals are also attached as a reference for Action Item CMC-A-2014-11-08. Finally, for Action Item CMC-A-2014-11-09, the following is the link to the Planetary Communication System project (please make sure you are logged in):

http://cwe.ccsds.org/fm/Lists/Projects/DispForm.aspx?ID=377&Source=http%3A%2F%2Fcwe%2Eccsds%2Eorg%2Ffm%2FLists%2FProjects%2FAllItems%2Easpx&ContentTypeId=0x0100B63160D64FE81342BE42A874DE7E703D

Deadlines for each of the action items are highlighted. Other action items assigned to the CMC that are not as urgent will be circulated at a later date.

CMC-A-2014-11-03

The CMC members were requested to review Nestor Peccia's chart on resources needed for the short term and provide a response to the Secretariat. The Secretariat was also instructed to circulate the chart to observers for potential contributors.
