<p class="MsoNormal">Okay, the SSF book has been Blue for a couple of weeks now – time to start compiling a list of possible errata
<span style="font-family:Wingdings">J</span>.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the process of collecting/defining the configuration information for the TDM Segment Generation functional resource (the primary production resource for TD-CSTS), I discovered that the
<i>Tracking Data Message</i> Blue Book (which defines the contents of the TDM atomic segments that the TDM Segment Generation FR produces) specifies four normative types of angles:<o:p></o:p></p>

</span></span><![endif]>AZEL<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>RADEC (right ascension, declination)<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>XEYN (X-east, Y-north)<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>XSYE (X-south, Y-east)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the SSF we have two “Antenna Pointing Angles” service types:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>APA-AZ/EL<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>APA-X/Y<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">AZEL is obviously by the APA AZ/EL “service”, and one could make the case that whether APA-X/Y refers to XEYN or XSYE is defined and fixed by the Service Agreement. But what about RADEC? Should that (eventually) be added to the list of
SSF service types: APA-RADEC?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">At least for now I’m going to include the 4 TDM flavors in the specification of the TDM Segment Generation FR, which will then also be part of the Configuration Profiles. If all 4 remain there will may have to be some adjustment to the
SSF down the road.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best regards,<o:p></o:p></p>
