EXTRACTING COMPACT RINEX FORMAT

Most IGS* stations archive data in compact rinex format.

I have had a hard time figuring out how to decompress this files.

Just follow the following steps:
1. Download RNXCMP_4.0.4_Windows.tar through this link:

2. Extract the bin folder contains the following files:











2. Save the following scripts as Windows batch file (example: 00D_00o.bat) to the same folder where you have saved the compact rinex files and the extracted bin files from RNX 4.0.4 Windows tar file above.
