Today, WG1 is mixing space downstream andupstream activities


Since 2015 downstream standards
developed in WG1 (see Back Up Slides=> 7/33 downstream projects)However engineering competencies ,industries and operators are not the samefor both streams

Downstream activities need to be addressedin a specific WG with clarified scope to:Federate experts, industries andoperators in this domainHighlight and strengthen downstream
activities in ISO/SC14

Develop common international
downstream standards to promote thismarket (which is also pulling globalSpace market)

Support large-scale deployment of
space services and applications,
including safety and critical ones (egdisaster management)

QUESTION

Which standards could be hosted by the newgroup?

ANSWER TO
PLENARYCOMMENTS
1/2ANSWER-12 candidates in total. Project Leaders decide hostWG according to Form 4 and relevant forms.

7 existing:ISO 18197, ISO 20930, ISO 22591, ISO 24246
ISO 24245, ISO 13657, ISO 16215-1
5 potential identified:
NWIP from European EN -1, -2, -3 and -4.
-see details (title, date) in slides 8-9-10-11 inside thisdocument

COMMENTANSWER TO
PLENARYCOMMENTS
2/2

Some satellite communication standards and GNSS
standards are already hosted by other WG. We
need to avoid duplication.
ANSWER-As a reminder, this new WG would deal withdownstream standardization (see slides 5 & 6 Rationales in this document).
-All parts dedicated to upstream (satelliteoperation, launching,…) will not be addressed by
the new WG.

-In order to be sure to avoid useless work, liaison
could be establish with the following WG:
ISO TC204 , ISO TC211, ISO TC20/SC16, 3GPP, RTCM,NMEA
