OK Adrian, all is clear and agreeable. I've already contacted Larry and asked
him to prepare an Agenda for a session in London for half a day (Thursday)
using existing SOIS rooms, if longer is needed we may need to request an
extra room. I have specifically requested that an Agenda point needs to be a
justification for X-support and if CCSDS is the appropriate platform for the
work. I have no particular feeling on this as of yet, so lets wait and see.
On the P&P aspect, I am a little uncomfortable with AFRL being the only
participant as they are not a NASA centre? If you mean that AFRL can fund
participants from NASA and NASA centres are willing to sign up then we have a
much better case for moving forwards. Regardless, we will have a P&P session
in London chaired by Stuart's deputy, Peter Mendham (Stuart is out of the
country that week on Vacation)

RE: re:Interest in forming a BoF to

Chris: I agree that we should keep the scope focused on defining exactly what
we would propose to internationally standardize in association with a
software-defined spacecraft radio. Therefore, SOIS appears to be the right
initial home for the activity. After we have understood this more narrow
application (and whether or not there *is* value in a standard), we can then
decide if the work should be expanded or should migrate to another Area (SLS
also seems to be a possible candidate). We might also decide that CCSDS isn’t
the right home. In order to get to those decisions, we need a much clearer
picture of the problem and proposed solution. I have therefore asked Larry
Foore to take up your SOIS hosting offer and to work with you to raise the
BOF in London.
I am also pleased to see the renewed interest in moving forward on the
plug-n-play work. We have literally zero NASA standards resources to apply to
this problem but I agree that it offers a realistic way forward and I
understand from Jim Lyke that the Air Force Research Lab is willing to
shoulder some of the burden. Can we assume that – as Chair of the SOIS PnP
BOF – Stuart will be calling a meeting in London?
By the way, the SpaceOps video on CCSDS and DTN just got posted to the NASA
public website:

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,
Regards,

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

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
