One might expect closer agreement if all of the receivers were fed from
one antenna through a splitter, but even then each rx will choose its
own series of constellations and will switch constellations at different
times. There will also be phase dispersion among the rx input filters.
And lots of other small effects.
one might so expect. But I'm not too sure.
There's >10 meters difference in the positions (in the X coordinate of
the ECEF position alone).
They're all tracking the same satellites (except b203)
but the S/N is noticeably different among them.
