position then.<o:p></o:p></span></p>

<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>
wrt PLOP-1, ESA propose to include a statement like the one we
have in ECSS-E-ST-50-04C(31July2008)</span> <br>
<br>
<span style='font-size:10.0pt;font-family:"Palatino Linotype","serif"'>a.
PLOP–2 should be used in preference to PLOP–1. </span><br>
<span style='font-size:10.0pt;font-family:"Palatino Linotype","serif"'>NOTE
PLOP–2 supports a higher data throughput on the physical telecommand
channel. PLOP–1 is included here for completeness and is used, for
example, by ground systems and for cross support. </span><span
style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br>
<br>
We can discuss this in ESTEC</span> <br>
