Is there any tool to do the reverse conversion R3 -> R2.x? If so, could you point me to?

Thanks, Octavian

Thanks for your interest in the GPSTk. At this point we do not have an R3-R2 down conversion application, though this is a desired feature and on the "to do" list. You might want to investigate TEQC by UNAVCO which may have this capability (

Dear David,

Thank you for your replay.

I do not need a very special convertor. If there are some hints how I could take advantage of the Rinex3 gpstk source code would be great. I have a R3 data file and I would like to extract into a R2.x only the L1 and C1/P1 data.

Hi. I just wanted to confirm whether this is still the case. it seems all the parts required already exist. am I overlooking something? a standalone utility for the conversion of rinex version 3 to rinex version 2 would seem an important niche that gpstk could fill-in imho.

Hello Felipe,

Down-converting a RINEX v3 file to a RINEX v2 file can be done using the RinEdit application with an additional optional argument. RinEdit is an application that opens and reads v2+ RINEX observation files, applies editing commands, and writes out a modified RINEX file. By default, RINEX will output the modified RINEX data into a RINEX v3 file, but adding the -ver2 optional argument will change the output to RINEX v2 file.

Documentation for the application can be found in the User's Guide (

Hope this helps, and let us know if you run into any issues using the application.

Thanks for your interest in the GPSTk.

Thanks, Bryan.

Bryan, I just downloaded the Windows binaries but can't seem to find RinEdit.exe in it. Am I missing something? I do see rinexthin.exe, RinSum.ex, etc. Thanks.

Hello Felipe,

Just to check, I just installed a fresh copy off of the Sourceforge windows file and I can see RinEdit in the binaries folder (between RinDump.exe and rinexelvstrip.exe). You should have 84 items in your binaries directory. If not, the install may have encountered a problem, and a quick uninstall and reinstall should hopefully fix the problem. Let me know how things work out for you.

Thanks, Bryan

I installed v2.1 and now all the 84 executables are there. For some reason, the download I did two days ago (using SF's "Looking for the latest version" link) returned v1.7, weird. Thanks once again.
