<span style=" font-size:12pt;font-family:Arial">Dear Steve,</span>
<br>
<br><span style=" font-size:12pt;font-family:Arial">in the context of the
CCSDS-OMG liaison I would like to inform you that during the last CCSDS
Technical Meetings in Gaithersburg (09-13 April 2018) reservations had
been raised on the proposed OMG standard (RFC):</span>
<br>
<br><span style=" font-size:12pt;font-family:Arial"><b>Satellite Command
& Control Message Specification (C2MS).</b></span>
<br>
<br><span style=" font-size:12pt;font-family:Arial">In particular, three
space agencies via their members in the CCSDS Spacecraft & Control
Working Group have identified notable overlaps between the above perspective
document and the on-going work of the working group on Mission Operations
(MO) Services. These Space Agencies (CNES - French Space Agency, DLR -
German Space Agency, and ESA - European Space Agency) are producing a Technical
Note to substantiate the overlap, which will be available in the second
half of June. </span>
<br>
<br><span style=" font-size:12pt;font-family:Arial">Clearly, in the spirit
of the liaison, both CCSDS and OMG should strive to avoid overlaps and
duplications, in favour of reciprocally adopting relevant standards, as
already done for instance by the CCSDS with the adoption of the OMG XTCE
standard.</span>
<br>
<br><span style=" font-size:12pt;font-family:Arial">Sincerely,</span>
<br>
