Scott from the OGC has noted the importance of this topic and invited us to raise the topics at the next OGC Technical Committee meeting at Banff (9 Sept).

I have a question about the WGS84 datum ensemble in regards to GNSS
receivers. When providing WGS84 locations, how would I know which
WGS84 variant is being supplied? Is the receiver involved in this? Or
is it the satellites that control this? Is it enough to know the date
of the measurement? Or must one track more to know which WGS84 variant
is provided?
