[gpsd-users] ✘ZED-F9T vs. NEO-M8T

[Gary E. Miller]

Yo All!

I was recently asked how the ZED-F9T compares to the NEO-M8T.  So
I pulled up some 12h scatter plots.  See attached.  The plots
are interesting.

Notice that the overall, 12 hour, results are very similar.  A CEP(95%)
os about 4 meters.  The medium term (10 minute) wandering also seems
about the same.  

The big improvement of the F9T seems to be in the high frequency
(seconds) jitter.  It seems the L1/L2, and multiple GNSS, signals
really damp down the short term jitter.  You can see this with cgps
as a more stable lat/lon.

Neither is good enough to put your car in the lane, no matter how
good your maps are.
