[time-nuts] Best GPS 1PPS Accuracy

Can someone explain the accuracy numbers that are represented in specs for GPS


I find that Trimble says the Resolution T
(http://www.trimble.com/resolutiont.shtml) has 15 ns (1 Sigma) like the M12+.


So I guess the real question is; are you comparing apples to apples when the
standard deviation (Sigma) is specified?


Another question is; what's the most accurate GPS receiver module available? I
realize this is only as accurate at the antenna system, but I'll save a
multipath discussion for later.
