[Sois-wir] CCSDS: Agreement between SOIS Wireless and SLS Placom working groups

[Kevin K Gifford]

Chris -

Thank you very much for your assistance in this regard.  The CESG clarification is timely and needed.

I have one observation which might become relevant.  Regarding the agreement for SOIS that:

   "SOIS Responsibilities include: A) networked multi-point links utilising commercial wireless network technologies for Communications onboard a space vehicle or habitat and/or surface links within the proximity of that vehicle or habitat"

There may be some debate over the exact definition of "proximity", e.g., how far from a planetary wireless infrastructure point.  I'm thinking of the "golden scenario" of a rover traversing several kilometers from a planetary surface infrastructure point.  I think (stating my view, not committing anyone else) that planetary surface communication networks and infrastructure (e.g., surface communications networks) are the domain of SOIS and anything space-to-ground is SLS.

The argument that I would like to avoid is: "Well, the rover is X km from the habitat so the communications link is the responsibility of SLS, even though the communications are all over the ground network."

I'm probably being somewhat anal, but we've gone round-and-round with Jean-Luc Gerner in this regard previously.  I guess we can cross this bridge if/when we come to it.

Thanks again Chris, very much appreciated.

Kevin

Dear Colleagues,

Please take note of the agreement below between CCSDS SOIS-Wireless and the PLACOM group.

________________________________



Dear All,
       I would like to inform you that, with respect to the overlap issue discussed in the CESG, today SOIS and SLS Area have agreed today the following split of responsibilities:

__________________
SLS Responsibilities include:
1) point-to-point links for Planetary Communications
2) multi-point links for Planetary Communications utilising CCSDS data link and physical layer protocols
3) consideration of usage of Radio Frequency bands over space-ground and space-space links

SLS can therefore define mission scenarios/profiles for Planetary Communications, as well as functional & performance requirements and develop the pertinent Standards (Magenta or Blue Books) according to the points 1..3 listed above.

SOIS Responsibilities include:
A) networked multi-point links utilising commercial wireless network technologies for Communications onboard a space vehicle or habitat and/or surface links within the proximity of that vehicle or habitat.
B) cooperation with the SLS Area for matters related to usage of Radio Frequency bands

SOIS can therefore define mission scenarios/profiles for Vehicle and vicinity Communications, as well as functional & performance requirements and develop the pertinent Standards (Magenta or Blue Books) according to the points  A..B listed above.

Charters and CWE Projects of the affected WGs in SLS and SOIS Areas are to be made consistent with the above set of responsibilities (if not consistent now).
