<p class="MsoNormal">3. You are of course welcome to discuss and present the ODM revision drafts within Message (proposed name) is a direct result of a decision by the CCSDS Navigation WG during the CCSDS-mandated 5 year review of the ODM standard. This review
process has 3 outcomes: reconfirm, retire, revise. "Retire" was obviously inappropriate, and we had several requests for revisions, so "reconfirm" was also not appropriate. "Revise" was the consensus decision. We are currently very early in the revision
process and I believe it is impossible at this point to correctly predict exactly what will emerge from the process. As you have noted, several of my comments suggest discussion of specific points at Darmstadt... I don't see this as any kind of weakness whatsoever.
It means that I think it will be more productive to entertain a face-to-face discussion on those matters rather than an email discussion.<o:p></o:p></p>

<div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">My comments are broad and cannot be expressed with respect to specific clauses.<br>
<br>
First, the Mean Elements Message should be deprecated. The intent was to supplant the Two Line Element Set with more efficient and widely applicable format. Russia, for example, uses a different mean element model, and several providers use models descended
from Paul Cefola's DSST model based on equinoctical elements. The goal was not achieved. TLE's persist and are incontrovertibly institutionalized despite their well demonstrated deficiencies.<br>
<br>
Second, the Orbit Hybrid Message should be omitted. There are many substantive comments on the proposed Hybrid message whose resolution is to defer until the next meeting. In addition, a standard with a preponderance of optional elements is not a standard.
We faced a similar issue with the CDM. What is required is consensus on the minimum necessary for effective use. The credibility of a provider is questionable when essential information is missing. Optional elements are not the prerogative of the provider.
They must be negotiated between provider and recipient. This not a standard; it is an ICD. Anything private between two parties is not a standard. In fact, 26699 states that it is a guide for those who wish private agreements.<br>
<br>
Finally, SC14/WG3 is the designated parallel developer, demonstrated by the agreement between SC13 and SC14 that led to the ISO registration with an SC14 designator. This must be negotiated among SC14/WG3 members.<br>
<br>
Respectfully,<br>
<br>
Dave Finkleman<br>
