<p class="MsoNormal"><span lang="EN-US">Dear SLP WG,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">** Here is an update on the 3 NASA-JSC RIDs proposed above in italics below **<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><i><span lang="EN-US">My preference (Greg as WG chair) would be to 1. Reject the first RID, since the C&S WG supplied that information which is useful and putting it into the AOS GB makes it less assessable. Reject RID 2, because there
was no change to it in the Pink Sheets and no missions have complained about it – plus see additional info below. Accept RID 3, since the first 10 bytes of the OID sequence is indeed duplicated on that same page, ergo it should only be mentioned once.<o:p></o:p></span></i></p>
<p class="MsoNormal"><i><span lang="EN-US"><o:p> </o:p></span></i></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black;background:yellow;mso-highlight:yellow">Again, your comments are welcome. The AOS SDLP (CCSDS 732.0-B) pink sheet review ends Dec 11, 2023.</span><span lang="EN-US" style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I have received 3 additional (besides Andrea Modenini’s RID, which we discussed in The Hague) from NASA which I would like to get your comments on.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">URL of the pink sheets are at:
<a href="https://public.ccsds.org/review/CCSDS%20732.0-P-4.1/732x0p41.pdf">https://public.ccsds.org/review/CCSDS%20732.0-P-4.1/732x0p41.pdf</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The first one, </span><span lang="EN-US" style="color:black;mso-ligatures:none">NASA-JSC-RID00</span><span lang="EN-US" style="color:black">1, requests a reduction in the amount of information provided. Since the C&S
WG provided this input, I’ve asked Ken Andrews (who supplied that change), NASA to give me his opinion on how to proceed. Your input is also welcome.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">The 2<sup>nd</sup> one, </span><span lang="EN-US" style="color:black;mso-ligatures:none">NASA-JSC-RID00</span><span lang="EN-US" style="color:black">2,
</span><span lang="EN-US" style="color:black;mso-ligatures:none">recommends to define “all ones minus one”. This requested change would actually have an impact in several locations in AOS SDLP but also in USLP.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black;mso-ligatures:none">My take on this RID is not to explicitly “define” it, because one can easily use a binary calculator to determine that “all ones minus one” equals decimal 254. Also since the FHP
field could be 11 bits (legacy implementations) vs 16 bits (new implementations), the “all ones minus one” terminology works in both cases, without having to spell out specific decimal or binary sequences of bits.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black;mso-ligatures:none">The 3<sup>rd</sup> one, NASA-JSC-RID00</span><span lang="EN-US" style="color:black">3, recommends removal of some duplicate information in Annex D, however, I believe that information
was duplicated with the intent to help the user understand the output of the OID Frame Randomizer up front, so I don’t have a strong reason to remove it or to leave it. I also asked Ken Andrews (who supplied that change) to comment on this RID as well.
