### To evaluate an NMEA file against another NMEA file:
Use Nmea2RtkMetrics.m to compute position accuracy metrics from two NMEA files:

dir='./NmeaUtils/example/';
refFileName='MTV.Local1.SPAN.20200206-181434.gga';
testFileName='MTV.Local1.ublox-F9K.20200206-181434.nmea';
Nmea2RtkMetrics(testFileName,refFileName,dir)

This will lead to the following output:

50% (m), 95% (m), TT1M (s), TA1M (s), AA5S (m), AA10S (m), XTrack 50% (m), XTrack 95% (m)
0.49, 0.81, 0, 0.91, 786.00, 0.91, 0.09, 0.27

Use Nmea2ErrorPlot.m to generate CDF of horizontal error:

Nmea2ErrorPlot(testFileName,refFileName,dir)
