[FOSS-GPS] Post-processing RINEX to simulate RTK

Dear Antonio,

I'm not an expert too. I am working on the same direction as you.
If you have logged RTCM to, I think RTKLIB can be used, there is an stream server that take receiver data from files.  
- STRSVR, STR2STR: communication utility.
Take a look on:

Or you can post-process as kinematic and use the processed output, but it will not be real-time as you want.

good luck !

Sorry if
this is not the right forum to post my question. I’m a newcomer and I am not by
no means a GNSS expert. But I want to learn. 


I want to
evaluate the quality of RTK differential phase positioning for some very demanding
engineering applications. Unfortunately I was not able to connect rover and reference station to the same computer, so I could not use commercial GNSS software to do the RTK processing of the observations. As a workaround I decided to store the observations (collected at both sites) in RINEX format files. Now I have a bunch of RINEX files, obs (phase at 20 Hz) and
nav, from base and rover.
I want to simulate real-time (as if they were
obtained in the field) double-differences double-frequencies phase
positioning of the rover by processing these RINEX files. I also need one position
for each epoch of observations and, for now, I do not want to use any kind of “smoothing
filter”. Can I use a post-processing application to do the job ? If this is not
possible, can you explain me why?







PS:  Some days ago I’ve found RTKLIB. It’s a very
interesting application. It would be nice if I could use it to solve my
