<p class="MsoNormal"><b>From:</b> Oltrogge, Daniel <br>
<b>Sent:</b> 31 Oct 2017 09:38<br>
<b>Subject:</b> Requesting your input on proposed SANA entries in support of future CCSDS International standards for space data exchange<o:p></o:p></p>

<p class="MsoNormal">Flight Dynamics, operations and astrodynamics colleagues – <o:p>
</o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Space Assigned Numbers Authority (SANA) is the registrar function for the protocol registries created under the Consultative Committee for Space Data Systems (CCSDS). I support the Navigation Working Group (Nav WG) within CCSDS, and
we develop international standards for data exchange of navigation-related elements of information.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are currently exploring the use of the SANA registry as a “living” reference support document to contain definitions of content that are currently duplicated (sometimes inconsistently) across many of the CCSDS standards. The concept
is to have the next generation of CCSDS standards instead reference the SANA registry as the single unified and up-to-date source for definitions of parameters.
<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I would like to get your input on the attached proposed table of entries for definition of:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">(1)<span style="font:7.0pt "Times New Roman"">

<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">(2)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Orbit element sets;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">(3)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Absolute and relative reference frames;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">(4)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Attitude and attitudinal dynamics definitions and parameters;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In each table, you can see the proposed “key” name and its associated definition. What I’d like to know is: Do the attached tables and content define what you are currently using operationally? Is there anything missing (again that you
are <u>actively</u> using in your operations) that you would like us to consider including in these tables?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If so, please let me know this week for inclusion into our CCSDS Fall meeting discussions next week.<o:p></o:p></p>
