<font size=2 face="sans-serif">Dear All,</font>
<br><font size=2 face="sans-serif"> there
is an ongoing update for CCSDS 320.0-B-6 CCSDS Global Spacecraft
Identification Field Code Assignment Control Procedures. Blue Book. Issue
6. October 2013.</font>
<br><font size=2 face="sans-serif">That document defines the acronym GSCID
corresponding to the term "Global Spacecraft Identifier"
being the concatenation of the 2-bit Version Number
(VN) and the SCID. </font>
<br><font size=2 face="sans-serif">To be able to allocate more values,
the update of CCSDS 320.0-B-6 would link the assigned value to the Frequency
Band actually used by the spacecraft.</font>
<br><font size=2 face="sans-serif">A possible consequence is that the use
of the tern GSCID will be discouraged/deprecated for future use.</font>
<br>
<br><font size=2 face="sans-serif">Note that some SLP documents (*) define
that "The concatenation of a TFVN and a SCID is known as a Master
Channel Identifier (MCID),"</font>
<br><font size=2 face="sans-serif">With TFVN (transfer Frame Version Number)
being actually the same of the VN mentioned in CCSDS 320.0-B-6 </font>
<br><font size=2 face="sans-serif">(*) CCSDS 132.0-B-2, , CCSDS 232.0-B-3,
CCSDS 732.0-B-3. Moreover MCID is mentioned in CCSDS 133.0-B-1</font>
<br>
<br><font size=2 face="sans-serif">Just to evaluate the possible impact
that updating CCSDS 320.0-B-6 could have on SLS documents, could you ALL
please check and report if any document of your Working Group is using
the term GSCID or the term MCID?</font>
<br>
<br><font size=2 face="sans-serif">Thank you and best regards</font>
<br>
<br><font size=2 face="sans-serif">Gian Paolo</font>
<br>
<br><font size=2 face="sans-serif">PS The only effect I can dream about
right now, is adding a note in those document to inform that the MCID is
called GSCID in CCSDS 320.0-B-6......</font><PRE>This message and any attachments are intended for the use of the addressee or addressees only.
