[CESG] re:Interest in forming a BoF to follow up on SDR standardisation?

Dear all,, I haven't replied yet to the initial interest in this topic but I
have done a little background digging here and at ESA we would be interested
in investigating the original target of SDR.  I have no problem to host the
discussion in the SOIS area and would propose an agenda item on the Thursday
for which we will free an existing SOIS room.

If Peter wants to take on the more ambitious activity of a standardised
platform in SEA this is fine by me but this is a very large undertaking and
I'm not so sure we are in a position to proceed.

What we have been working on at ESA, to a large extent driven by CCSDS SOIS
but also as part of our SAVOIR coordination activity with industry,  is the
identification of avionics building blocks with well defined interfaces and
functions. A good example of this is a mass memory unit complying with SOIS
file and packet store services supported by ECSS defined protocols for
Milbus, CAN and SpaceWire. We are busy mapping this to the packet utilisation
standard (PUS) used over the space link in support of file based operations.
As part of our DTN/CFDP implementation activities we will use a prototype
mass memory implementation to further verify the setup.

After some delays, which have slowed the work in SOIS, we have just secured
funding for related activities on the use of electronic data sheets and plug
and play protocols, and I would suggest that this offers a more realistic way
forward in harmonising our onboard systems.

Lots to discuss I guess,

I think it is time to take a serious look at this and cannot think of another
organization in which we could do it and produce a result that will be
meaningful to our civilian space agencies.  Since calling it “reconfigurable,
modular, interoperable communications platforms” sounds rather cross-cutting
and the product is likely to be a recommended practice or a reference
architecture rather than a single discrete protocol spec, I would consider
housing it in SEA.

Regardless of where it winds up it will be essential to include the
perspectives, and the experts, of other areas and other working groups.

      Jean-Luc, Chris, Peter: following lunch-time his talk at the Portsmouth
      meeting, Larry Foore of NASA-Glenn has been leading an activity over
      the summer to identify if there is potential interest in CCSDS in
      forming a BOF to study the possible standardization of “software
      defined radios”. I understand from Larry that as an outcome of these
      discussions it has been proposed to broaden the scope from SDRs to
      reconfigurable, modular, interoperable communications platforms in
      general.

      There has been considerably US interest in this subject but I
      understand from Larry that only one person from another Agency (ESA)
      became engaged over the summer (this may of course be because of the
      holiday period). We therefore need to decide whether to “raise a BOF”
      at the London meeting. If we do, we need to decide to which Area it
      would be attached. Do any of you have sufficient interest to call such
      a BOF? If not, we should drop the subject. Please indicate your
      interest:

      Best regards
      Adrian

      Subject: [Sois-wir] Interest in forming a BoF to follow up on SDR
      standardisation

      Dear SOIS members,

      There is currently a proposal before the CCSDS Engineering Steering
      Group (CESG) to form a Birds-of-a-Feather group (BoF) looking into the
      interest in standardising on Software-Defined Radio (SDR) in the Space
      domain.

      If you have any interest in participating in such a BoF please could
      you let me know by the end of 13 July 2010 so I can report this back to
      the CESG.

      Regards,

      Stuart D. Fowell BEng MBCS
