<font size=2 face="sans-serif">Dear Bernie,</font>
<br><font size=2 face="sans-serif"> first
of all let me wish you and all the OCMers an happy 2013.</font>
<br>
<br><font size=2 face="sans-serif">Thank you for your reporting about IOAG
intentions.</font>
<br><font size=2 face="sans-serif">Following this information, unless some
agencies express "soon" interest for an OCM convocation and propose
a suitable agenda I assume there will be no SLS-OCM meeting at the Spring
2013 CCSDS in Bordeaux.</font>
<br>
<br><font size=2 face="sans-serif">Comments are welcome.</font>

<br><font size=3 face="Calibri">Hi!</font>
<br><font size=3 face="Calibri"> </font>
<br><font size=3 face="Calibri">This is Bernie Edwards from NASA again.
I just wanted to let you know that the Optical Link Study Group (OLSG)
Recommendations were presented at last week’s Interagency Operations Advisory
Group (IOAG) meeting at Kennedy Space Center. </font>
<br><font size=3 face="Calibri"> </font>
<br><font size=3 face="Calibri">IOAG is recommending that CCSDS not do
anything with optical communications at the April CCSDS meeting. Instead
OLSG will do some additional work, but minimal, between now and IOP-3 in
the summer of 2013. The IOAG requested an updated roadmap, an
estimate of the effort needed (financial resources) for CCSDS standardization
that is required, and for the OLSG to produce a reduced set of core optical
communication standards recommendations. At the IOAG, a reduced core
set was discussed to be something along the lines of:</font>
<br><font size=3 face="Calibri"> </font>
<br><font size=3 face="Calibri">
Downlink Modulation (PPM, BPSK, DPSK)</font>
<br><font size=3 face="Calibri">
Meteorological Measurements</font>
<br><font size=3 face="Calibri">
Protocols</font>
<br><font size=3 face="Calibri"> </font>
<br><font size=3 face="Calibri">However, the IOAG really asked the OLSG
to go back and look at it and come back with a recommendation. Basically,
in my opinion, the IOAG thought that the OLSG recommend too many “high
priority” standardization areas and the IOAG wanted to see which of those
were more important than others.</font>
<br><font size=3 face="Calibri">
</font>
<br><font size=3 face="Calibri">So there will not be an Optical Comm BOF
or SIG within CCSDS until sometime after IOP-3, which takes place this
summer. However, some have suggested holding some type of unofficial
workshop just to keep dialogs going. Stay tuned!</font>
<br><font size=3 face="Calibri"> </font>
