Here is the data of the test over 10 Minutes:


The .txt files are the raw data streams with the ubx / rtcm data and i also
added the converted .pos / .nav files.
And what i didn't write is that i use the windows version. I have used the
linux console version earlier and i got the same results.
I also took a screenshot on how the window looks during the test, which i
forgot to add in the last message:


I access the base station computer via ssh on a linux laptop, which sends
the data via UDP to a specified IP. Because RTKLIB only supports TCP, I use
netcat to forward that data via TCP to my windows Laptop which i then take
outside with the Rover GPS attached to it. But all that works with no

And i have never heard of valgrind, but i looked it up and should be able to
test with it. I only interpreted the debug data i had together with the
source-code, so the problem might be somewhere else, but i am pretty sure
that it's there.
