`rnx2crx` is a small command line utility to compress
your RINEX files to CRINEX (Compact RINEX) files. It is modern
replacement of the historical tool.
This tool is based on the [GeoRust/RINEX parser](https://github.com/georust/rinex).
:warning: this tool is work in progress
## Download the tool
You can download the latest version from [the release portal](https://github.com/rtk-rs/rnx2crx/releases)
## Install from Cargo
You can directly install the tool from Cargo with internet access:
```bash
cargo install rnx2crx
```
## Build from sources
Download the version you are interested in:
```bash
git clone https://github.com/rtk-rs/rnx2crx
```
And build it using cargo:
```bash
cargo build --all-features -r
```
Getting started
===============
The tool expects one input file that needs to be a valid Observation RINEX file:
```bash
rnx2crx AJAC3550.21O
Compressed AJAC3550.21D
```
By default the tool lets you know what the output file is (`stdout`).
If that bothers you, simply use `-q` (quiet option):
```bash
rnx2crx -q AJAC3550.21O
```
RINEX Revision
==============
The tool supports RINEX V2, V3 and V4.
It will preserve the input format by default, so standardized V3 filenames will produce a standardized file name:
```bash
rnx2crx ACOR00ESP_R_20213550000_01D_30S_MO.rnx
Compressed ACOR00ESP_R_20213550000_01D_30S_MO.crx
```
We have one option that let's you convert a V3 format to V2 directly:
```bash
rnx2crx -s ACOR00ESP_R_20213550000_01D_30S_MO.rnx
Compressed ACOR3550.21D
```
## Custom output name
You can specify a custom output location with `--prefix [directory]`:
```bash
rnx2crx --prefix /tmp -s ACOR00ESP_R_20213550000_01D_30S_MO.rnx
Compressed /tmp/ACOR3550.21D
```
You can specify a filename yourself with `-o [filename]`,
which overrides any filename determination logic:
```bash
rnx2crx -o TEST.txt ACOR00ESP_R_20213550000_01D_30S_MO.rnx
Compressed TEST.txt
```
## Gzip files
The tool supports gzip compressed CRINEX files natively, but can only generate
"plain" CRINEX at the moment:
```bash
crx2rnx ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz
Compressed ESBC00DNK_R_20201770000_01D_30S_MO.crx
```
## Compression customizations
We support several option to optimize your compression scenario:
1. `-d YYYY-MM-DD` let's you customize the CRINEX compression date.
When `-d` is not specified, we use the system time:
```bash
rnx2crx -q -d 2000-01-01 ESBC00DNK_R_20201770000_01D_30S_MO.rnx.gz
```
2. `-t HH:MM:SS` let's you customize the CRINEX compression time during that date.
When `-t` is not specified, we use the system time.
```bash
crx2rnx -q -d 2000-01-01 -t 01:02:03 ESBC00DNK_R_20201770000_01D_30S_MO.crx.gz
```
When Time is specified without Date, we use the date retrieved from system time and replace the time during that day.
