of interest as you did with the red dashed box for the SEA part? I certainly see the value and the message to the audience (“look I’m here and deal with these assets”), but I’m afraid it is a bit difficult for the other areas, since they are more or less all
going from one end to the other end, except probably SOIS. I think this could make sense if we take the animated version, remove the “lines and arrows” for the other areas and we keep those for our specific area.

all on-board. For SLS it is all over the space link, one link at a time.

recommended channel coding solutions are different. </span><b><span lang="EN-US" style="font-size:11.0pt;color:#3B7D23"><<I wanted to demonstrate that the bulk of our standards, which we designed in the RF world, will also work over optical (FSO) with little

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I took a cut at a “abbreviated” set of slides for the SEA intro at the LIF. I know we just have 10 minutes apiece.</span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I took the approach of using the “Kearney animated CCSDS graphic” as a starting point because I think it will provide a useful “map” of how this area fits into CCSDS. I’d suggest that we all
do the same and that if we do we can just throw it up on the screen, say “here is what my area provides” and then get to the next slide with WG details. I turned off animation to make this quicker.</span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">The second slide has “one-liner” sorts of details about the WGs in the area. I think that most of the areas will fit on one slide like this, SLS is (always) the notable exception. Ignacio probably
needs two such slides.</span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I added another slide which is the end-to-end DTN based architecture from the SCCS-ARD document. I think this is important because as an architecture slide it covers space, ground stations, user
MOC, and relay assets. It also covers SLS, SIS, CSS, and SEA, and provides some hints as to where MOIMS and SOIS attach to the comms layers. I did one quick overlay animation showing the two major interoperability points.</span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">And I added two more copies of that same slide, one with an optical comm link shown, the second showing a “bespoke” commercial deployment and those same two interoperability points. </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I think I can get through these in 10 minutes. And I think they will provide a map that all the rest of the areas can be located upon.</span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I assume that each of the other areas will have some sort of graphical content as well, or maybe we will all just use that same “Kearney” slide to show the crew where each area fits in. This
will be a little repetitive, but I think we can go over it quickly and get to the details. Maybe each area will also have some graphical view of some of its specific standards</span><span style="font-size:11.0pt"><o:p></o:p></span></p>
