[FOSS-GPS] RTKLib rover - base question

[Michele Bavaro]

Dear Aljaz,

Can you host a TeamViewer meeting having the receivers in place so that 
somebody can help you live?

Cheers,
Michele

With RTKPost I successfully opened the one from rover but the other from base contained no data after transformation (file .pos has only the header). Interestingly the original ubx files  for rover and base had different sizes (for the same length of time): rover - 1605 kB, base - 447 kB.

After some time of running it starts sticking - for shorter or longer periods of time there's no change in calculated position with no new points plotted. Afterwards it resumes (calculates and plots again). Normally if I stop and start the program again everything looks normal (as if some buffer gets full and needs to be emptied from time to time). My signal from satellites is ok so this shouldn't be a problem.
