<br><font size=2 face="sans-serif">Dear Nicolas,</font>
<br>
<br><font size=2 face="sans-serif">thank you for your reply.</font>
<br><font size=2 face="sans-serif">For the sake of clarity, I would like
to point out that, in my mail of 23.07, I was objecting to the minutes
produced after the meeting, not to the content of your presentation.</font>
<br><font size=2 face="sans-serif">I certainly don't ask to change the
view of your Institution, as contained in such presentation, whether I
agree or not. </font>
<br><font size=2 face="sans-serif">Nevertheless, it would be fair that
the moms reflect all the opinions expressed during the meeting. </font>
<br><font size=2 face="sans-serif">The way they are now (as published in
CWE), in my opinion, they don't mirror the discussions we had. </font>
<br><font size=2 face="sans-serif">If you wish, I can certainly provide
you with a summary of the points I raised in Virginia Beach.</font>
<br>
<br><font size=2 face="sans-serif">Best regards,</font>

<br><font size=2 face="Arial">Dear Massimo,</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">1) I agree that we should have a completed
version of the white paper as soon as possible.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">2) As you suggested, I will add the following
point on the agenda of the Fall meeting (London): “Discussion on the participation
of ESA to the OCM work and on ESA internal approval process”.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">3) About your objections during the Spring
meeting:</font>
<br><font size=2 face="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.</font>
<br><font size=2 face="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.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="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.</font>

Dear Nicolas,</font><font size=3 face="Times New Roman"> </font><font size=2 face="sans-serif"><br>
thank you for the draft.</font><font size=3 face="Times New Roman"> <br>
</font><font size=2 face="sans-serif"><br>
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.</font><font size=3 face="Times New Roman"> </font><font size=2 face="sans-serif"><br>
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.</font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="sans-serif"><br>
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.</font><font size=3 face="Times New Roman"> </font><font size=2 face="sans-serif"><br>
I would suggest coming back to this at the London meeting, after the technical
discussions are over.</font><font size=3 face="Times New Roman"> <br>

Massimo</font><font size=3 face="Times New Roman"> <br>
</font><font size=2 face="sans-serif"><br>
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</font><font size=3 face="Times New Roman">
</font><font size=2 face="sans-serif"><br>
in the minutes.</font><font size=3 face="Times New Roman">

Dear Lasercom people,<br>
<br>
Find attached a draft of the charter for the creation of a CCSDS working
group "Optical coding and modulations".<br>
Please send me your feedback within 3 weeks (till July, 26th). If your
agency is a CCSDS member agency, check whether it indeed supports the specific
scenarios as established in the last column of the scenario table.<br>
<br>
Regards,<br>
<br>
Nicolas Perlot<br>
Chair of the SIG "OCM"<br>
