Don't forget that PPS accuracy of a GPS receiver is theoretical best-
case some 50 ns; in reality, things can get a little worse than that.

It wasn't clear to me whether that was a *single* GPSDO whose outputs
were being distributed, or whether this
was individual B210s with on-board GPSDOs distributed over several
kilometers.
So, Stephan, which case is it?

Hi All,
I'm looking at using multiple B210s synchronized with GPSDO
distributed over a few kilometers. The idea is to measure time-of-
arrival of a signal source. I understand the limitations of the GPSDO
1pps & 10 MHz reference frequency/time stability.
What I'm curious about is whether anybody has done this, and whether
it worked without too much trouble. The only references I see of
distributed MIMO, is where NI recommends using the N210:

Any advice would be greatly appreciated.
