Here is my 1st draft of the following WG agendas for the Fall 2004 CCSDS
Meetings in Toulouse during the week of Nov 15 through Nov 19. Please note
that information about meeting location and lodgings in Toulouse is now
available on www.ccsds.org. Please also register for the meetings at that
This email concerns:
CCSDS SLS-SLP WG , CCSDS Link Layer WG, Build-2 Prox-1 WG
Please let me know if you have any additional topics you would like to add
to these agendas.
Draft SLS-SLP WG Agenda:
- Pink sheets against the AOS Space Data Link Protocol CCSDS 732.0-P1.1
We took this item up at our last meeting and received approval from CESG to
proceed. However, this item was not followed up on i.e., no formal pink
sheets were drawn up by the secretariat. I simply want to review these
changes to make sure they are still correct (to handle frame accountability
for missions reasonably to 150 Mbps e.g., Lunar Recon Orbiter) and cover
the changes to TM Sync and Channel Coding, if we ever envision an increase
of frame size beyond 16KB.
Possible joint Channel Coding and Link Layer topic concerning frame length
increase for TM Sync & Channel Coding
- Encapsulation Service RED-2
We also took this item up at out last meeting and received approval from
CESG to proceed. These changes would make the encapsulation packet header
compatible with microprocessors that require 32-bit word compatibility.
Draft Link Layer WG Agenda:
Concerns itself with the following Link Layer Green Books:
- The complete 1st issue of the Draft Proximity-1 Space Link Protocol Green
Book will be discussed at this meeting. I will circulate this document to
the WG members by email so you can review it before the meeting.
- Discuss any comments both internal to the WG as well as received due to
the review of the following link layer documents on the CCSDS web site.
Current versions of these documents are accessible from
CCSDS 130.0-G-1.1 Overview of Space Link Protocols Green Book
CCSDS 130.2-G-0.1 Overview of Space Data Link Protocols Green Book
Proximity-1 Build-2 WG:
Work here is currently on hold for now. We have completed all of the
revisions on the data link book which resulted in a new blue book and
completed the majority of changes to the physical layer but are awaiting
the results of an action item on the RF&MOD WG concerning the wording of
requirements on data rate accuracies and stabilities. The RF&MOD WG is
planning to meet during the week on Oct. 18 in Pasadena and I understand
they plan to take up this action at that time. The result of this action
item will effect this requirement in the Physical Layer of Proximity-1.
