<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

the white paper as soon as possible.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

on the agenda of the Fall meeting (<st1:City w:st="on"><st1:place w:st="on">London</st1:place></st1:City>):
“Discussion on the participation of ESA to the OCM work and on ESA
internal approval process”.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>If I remember correctly, you objected during my
presentation on direct LEO downlinks that GEO satellites with optical payloads
were already flying (ARTEMIS) or about to fly (Alphasat, EDRS). J-L. Gerner
also mentioned the need for onboard memory for direct optical downlinks. I
agree. But these remarks do not change the view of my institute DLR-IKN (and also
my view) on direct LEO downlinks. What I was presenting was the view of my
institute DLR-IKN, just like JPL, NICT and JAXA presented their views on
optical links. If ESA has different views which you are aware of, you are
welcome to present them.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>So the document I presented was a DLR-IKN document
supporting CCSDS discussion, but it was not a CCSDS document. So it does not
have to contain your remarks.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>4) I suggest to avoid the Post Scriptum in e-mails
and to keep the message content before the signature: I saw your P.S. only the
second time I read your message. I recognize, though, the usefulness of
P.S. for paper letters.<o:p></o:p></span></font></p>

<br>
<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>As
an ESA SIG member, it is my opinion that the creation of a new WG is still
premature, while the SIG should first finish the work it was supposed to do.</span></font>
<br>
<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>In
particular, I believe that the SIG should finalize the white book on
"Optical coding and modulation". Eventually, once the material is more
mature, a Green Book may be delivered.</span></font> <br>
<br>
<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>In
any case, some more time and supporting material will be necessary to
understand whether ESA can partecipate to the work, due to the internal
approval process.</span></font> <br>
<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>I
would suggest coming back to this at the London meeting, after the technical
discussions are over.</span></font> <br>

<br>
<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>P.S.
By the way, at the Virginia Beach meeting I raised a number of objections to
the assumptions put forward for some of the scenarios, i.e. LEO-ground, but I
couldn't find any trace of them</span></font> <br>
