<span style=" font-size:10pt;font-family:sans-serif">Dear All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">please find below
the response by NASA/GSFC on AI-20_02, -03 and -04.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I guess that response
to AI_20-03 may trigger further actions on the proponents of the relevant
recommendation.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Best Regards,
Enrico</span>

doesn't know of any planned missions with the 22 GHz uplink that are not
lunar missions, but would be ok with this being generic for all near-Earth
missions.</span></p>

the proposed modulations, GSFC has the following questions:</span></p>
<ul>
<li><span style=" font-size:11pt;color:red;font-family:Calibri">What is
the driver for the higher order mods on the uplink? </span>
<ul>
<li><span style=" font-size:11pt;color:red;font-family:Calibri">Are there
any mission profiles? </span>
<li><span style=" font-size:11pt;color:red;font-family:Calibri">Anyone
cares about spectrum on uplink?</span></ul>
<li><span style=" font-size:11pt;color:red;font-family:Calibri">What is
the requirement on the failure rates for the higher order mods?</span>
<li><span style=" font-size:11pt;color:red;font-family:Calibri">Do the
higher order mods for uplink need to be further analyzed?</span></ul><span style=" font-size:11pt;color:red;font-family:Calibri"> </span>

<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;color:red;font-family:Calibri">None,
