Crinex
CRINEX stands for Compressed RINEX. It uses a compression method developped by Y. Hatanaka for IGS.
This algorithm is developed solely for Observation RINEX files, it does not apply to Navigation files for example.
The CRINEX compression is not a lossless compression.
This toolsuite proposes
- CRX2RNX to decomprese a CRINEX into readable RINEX
- RNX2CRNX to compress Observations into a compact CRINEX
Both support the gzip compression natively that you can add on top for ultimum compression ratio.
Note that gzip'ed CRINEX are the prefered exchange format when it comes to post processing sampled GNSS signals.
