[FOSS-GPS] RTKPLOT - Difference in output

Hi Julio,

Thanks. Yes I am attaching the necessary files.
So my setup is such that I used one as a base and one as rover, both kept
approx 14 - 15 meters apart. Both are as input to RTKNAVI via serial and I
am logging data, baseline and lat/long/altitude in three different files
respectively.

I have attached 2 zip folders containing logs of 2 different config
options. Both are as "Moving Base", and hence no base position is required.
One folder is containing data for "continuous" ambiguity resolution setting
and the other for "fix and hold". Both capture only L1. Rest of the
settings are default.

Using the baseline file, I plotted the E/N/U values in excel. Using the
base and rover log files, I converted to RINEX using RTKCONV and then did a
RTKPOST followed by plotting using RTKPLOT. There is a difference between
baseline position plot in excel and RTKPLOT.

I am sharing all my files. I hope all this will help you to figure out what
is going on, what is right or wrong and what could be rectified and how
should it be taken forward.

Do let me know in case you need anything else.

Thank you once again.

Cheers,
Max
