CRX2RNX

crx2rnx is a small command line utility to decompress your CRINEX (Compact RINEX) files into readable RINEX. It aims at becoming a modern replacement of the historical tool.

This tool is based on the GeoRust/RINEX parser.

Download the tool

You can download the latest version from the release portal

Install from Cargo

You can directly install the tool from Cargo with internet access:

cargo install crx2rnx

Build from sources

Download the version you are interested in:

git clone https://github.com/rtk-rs/crx2rnx

And build it using cargo:

cargo build --all-features -r

Getting started

The tool expects one input file that needs to be a valid CRINEX file:

crx2rnx AJAC3550.21D
Decompressed AJAC3550.21O

By default the tool lets you know what the output file is (stdout).

If that bothers you, simply use -q (quiet option):

crx2rnx -q AJAC3550.21D

CRINEX V1/V3

Both revisions are supported by this tool.

The tool preserves the input format by default, so standardized V3 filenames will produce a standardized file name:

crx2rnx ACOR00ESP_R_20213550000_01D_30S_MO.crx
Decompressed ACOR00ESP_R_20213550000_01D_30S_MO.rnx

We have one option that let's you convert a V3 format to V2 directly:

crx2rnx -s ACOR00ESP_R_20213550000_01D_30S_MO.crx
Decompressed ACOR3550.21O

Custom output name

You can specify a custom output location with --prefix [directory]:

crx2rnx --prefix /tmp -s ACOR00ESP_R_20213550000_01D_30S_MO.crx
Decompressed /tmp/ACOR3550.21O

You can specify a filename yourself with -o [filename], which overrides any filename determination logic:

crx2rnx -o TEST.txt ACOR00ESP_R_20213550000_01D_30S_MO.crx
Decompressed TEST.txt

Gzip files

The tool supports gzip compressed CRINEX files natively, but can only generate plain RINEX at the moment:

crx2rnx ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz
Decompressed ESBC00DNK_R_20201770000_01D_30S_MO.rnx
