Hello Javier. I wrote rinexpvt. If you are looking to find the position of static receiver, PRSolve can do the job, and it is more robust. I note two problems: first the smoother debug output is nonsensical. It has numbers on the order of 10^300, it appears. Also, the nav file only appears to have data for PRN 1.

If you post you obs and nav files, I can run it through my version of rinexpvt and tell you if the problems are still there.

The comand is: rinexpvt -o lare021a.09o -n lare021a.09n
