[CMC] Re: [CESG] Re: [Sois-wir] [SOIS] Proposed way-forward for SOIS

[Chris.Taylor at esa.int]

Adrian, it seems to me that you are moving the goal posts and attempting to
change the rules of the game. We have followed CESG procedure and directives
to the letter - the Green book has been submitted to the CESG , reviewed and
updated accordingly and now, in accordance with CCSDS procedure, it should be
released.

At the CESG meeting the SOIS activity was fully discussed during the area
report. The resolutions proposed during the ESA presentation were not
questioned and the only point of contention was whether we go the Blue of
Magenta route. It was agreed that this decision would be deferred until all
Agencies had the chance to see the contents of the Red books.

Going back on these agreements, made in the presence of the CMC, is not
acceptable and I would respectively request that the CESG and the CMC remain
with the CCSDS decisions taken during the meeting. Anything else would make a
mockery of CCSDS procedures and reporting structures.

As far as the charters are concerned, they were updated and submitted to you
for review around November last year.  Finally, the two industrial support
contract we have in place to support the SOIS have now expired as far as the
green book is concerned, so we have 0 resources to  perform yet another round
of CESG updates.

Chris: I would respectfully point out that at this point time you don't have
approved charters for *any* of the SOIS work. The fact that you are moving
rapidly ahead without charters indicates that your contractual requirements
can clearly tolerate some uncertainty. Surely your contractual interests
would be far better served by CCSDS consensus than by a rush to publication?

My position is unchanged. I want the CESG to evaluate the *whole* SOIS
situation, all at once, not in piecemeal dribs and drabs. Then I want to CESG
to formulate a technical recommendation about the whole activity, and for the
CMC to act accordingly. I see no benefit to issuing a Green Book until that
holistic assessment is complete.

The Management Council is copied on this exchange. If the ESA delegate would
like to ask the CESG to forward the SOIS Green Book to the CMC for standalone
voting with a view towards early publication - without the benefit of a CESG
review of the rest of the SOIS work - I will of course be happy to
accommodate that request.

Best regards
Adrian

      Adrian, I am thoroughly against this and it goes back on our previous
      agreements. According to CESG directives, we have produced the Green
      book,
      had it reviewed at CESG level, made the updates accordingly and now it
      should
      go out without delay and in line with CCSDS procedure.

      There may well be a need to update the Green Book but only after we
      have had
      feedback from the draft Red Books in conjunction with prototyping but
      this
      will not be before the end of the year. This is in-line with the SOIS
      charter, which in turn is matched to our industrial support contracts
      and we
      have no resources available for another Green book review cycle, so I
      cannot
      commit to it.

      I also do not agree that this is the same as the Cislunar situation. We
      have
      3 Agencies actively participating in SOIS,  all representing flight
      systems
      and the SOIS group has an agreed brief to provide Red and Green books.
      At ESA
      and BNSC, the SOIS architecture is already being proposed for flight
      implementation, in addition,  we have contracts running for Milbus and
      Spacewire mapping. As I was at pains to point out in my report to the
      CESG,
      we therefore have contractual commitments that rely on a published
      green book
      and at least draft Red books, and any further delay will result in
      contractual problems.

      I therefore request that we stay with the previous agreements and
      publish the
      Green book.
