<p class="MsoNormal"><span style="font-family:"Georgia",serif">I have been poking around a bit in the SANA service sites and apertures registry and it seems to me that there is still a rather unfortunate lack of correct information in here. I mention this as
the SSF (simple schedule format) comes up for a 5 year refresh next year (yes believe it or not it was published as a standard in 2018). One of the critiques that I continue to hear from the implementation of the standard at the DSN is that the SSF refers
to the service sites and apertures registry as the proper source for identifying apertures in the schedule, but that the SSA registry does not really do this. The lack of substantially correct or incomplete operational information in the SANA registry continues
to impede the interoperability that the SSF should provide. And, additionally, we have the CDE M-2 out for agency review, and it also directs the reader to look up aperture information in this SANA SSA registry. Of course, we cannot “fix” the service sites
and apertures registry, but I believe it would be worthwhile to spend a bit of time at the Toulouse meetings to collect inputs for the CESG and CMC as to the nature of the updates that are needed for this registry.<o:p></o:p></span></p>
