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

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

      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
