The discussion was a combination of audio and typed chat. For this reason the chat transcript (given below) gives an incomplete representation and may be hard to follow.

Progress made: Very good progress was made through the working document. Sections B2.3 to B2.9 were all completed, with amendments agreed and made on the wiki. The only exception was the last comment in B2.4 from JohnGarrett, which was deferred and will taken into account for a possible additional requirement.

SimonLambert reported on behalf of DavidGiaretta that there is good progress to Working Group status. David will send an email soon on the subject. Everyone involved should check their declared commitment of effort - this is a requirement of CCSDS.


  • All to make comments on the remaining sections of B2 and onwards to B3.
  • SimonLambert to update the availability matrix for future weeks.
  • All to check their declared effort commitment on declared commitment of effort.
