[Sls-mhdc] MHDCA-1810-5 review CCSDS-121.0-B-3 draft

Mon Apr 22 07:43:12 UTC 2019

Dear working group,

I'm sending the following email today to all the implementers that I know and that are probably not subscribed to this mailing list (DSCAL, Airbus, Thalès, UCM, Udri, Deltatec.be, inaf.it...).
Please, feel free to send it to others you may know.

Kind regards

Roberto

Dear implementer of the CCSDS 121.0-B-2 standard (or the CCSDS 123.0-B-1), 

The Multi and Hyperspectral Data Compression Working Group (SLS-MHDC) falling under the Space Link Services (SLS) Area of the CCSDS, has identified the need to update the Recommended Standard CCSDS-121.0-B-2 “Lossless Data Compression”. 

This update is intended to resolve potential ambiguities in the current version of the standard. 

The principle for the intended changes, is to minimize the potential impact of resolving these ambiguities on existing implementations and related documents. 

Therefore, your collaboration is fundamental in order to obtain a complete survey of the choices done in all the existing implementations. 

We kindly ask you to answer the following survey about your implementation before May 6, 2019. 

If your implementation is Hardware (or both HW and SW), please follow this link: https://fr.surveymonkey.com/r/MY6XS92

If your implementation is Software, please follow this link: https://fr.surveymonkey.com/r/TKQGZMZ

Thank you very much for your valuable help. 

Kind regards,

 Dear working group,

  As promised in my previous email, you will find below the link for the survey including the list of questions intended for the implementers of the 121.0-B-2 (this should also include all the 123.0 implementers).

  https://fr.surveymonkey.com/r/TKQGZMZ

  Please take a look and let me know if you think something is missing or if the questions should be different.

  I'd like to start spreading the survey beginning of next week so that we can compile all the answers before the spring meeting.

  Kind regards,

  Roberto

    Dear working group, 

    As for MHDCA-1810-5 (d) "follow-up with current implementers", we are preparing a list of questions for implementers about the choices they made for the parts that looked ambiguous in the standard (and that we are planing to clarify in the B-3). 

    So, we have been through the document again and we have identified several issues that still seem to be open to interpretation, even in the revised document submitted in November (MHDCA-1810-5 (a)). 

    Could you please review the marked-up draft in "CWE Private\121.0-B-3-DRAFT\121x0b3-DRAFT-2019_04_04_ESA_comments.docx" so that we can reach consensus during the next meeting? (the plan is to take also into account the answers from implementers). 

    Thank you for your help & see you next month, 

    Kind regards, 

    Roberto
