RINEX

Rust tool suites to parse, analyze and process RINEX Data.

The Wiki pages is the main documentation portal. It contains several examples spanning different GNSS applications.

If you have any question or experience any problems, feel free to open an issue on Github.

Advantages 🚀

• Fast 🦀
• Open sources
• Seamless Hatanaka compression and decompression
• Seamless Gzip decompression with flate2 build option
• RINEX V4 full support
• Meteo RINEX full support
• IONEX 2D support. Partial IONEX 3D support.
• Partial ANTEX support
• Full support of High Precision Clock RINEX products
• Full support of SP3 High precision orbit products
• Several pre processing algorithms:
  • File merging
  • Time binning
  • Filtering
• Several post processing operations
  • Position solver
  • Graphical analysis
  • CGGTTS solutions solver
• All modern GNSS constellations, codes and signals
• Time scales: GPST, BDT, GST, UTC
• SBAS support
• High precision phase data (micro cycle precision) theoretically supported but not tested yet
• Quality Check (QC): file quality and statistical analysis to help precise positioning (historical teqc function).

Disadvantages ⚠️

• QZNSST is represented as GPST at the moment.
• We're waiting for Hifitime V4 to support GLONASST and IRNSST.
  Until then, orbital calculations on these systems are not feasible.
  In other term, positioning is not feasible and you're limited to basic analysis.
• These tools are oriented towards the latest revisions of the RINEX format. RINEX4 is out and we already support it. Some minor features in the RINEX2 or 3 revisions may not be supported.
• Our command line applications do not accept BINEX or other proprietary formats
• File production is not fully concluded to this day. We're currently focused on RINEX post processing rather than RINEX data production. Do not hesitate to fork and submit your improvements

Repository

• rinex is the core library

• rinex-cli : an application dedicated to RINEX post processing. It supports some of teqc operations. It integrates a position solver and can format CGGTTS tracks for clock comparison. The application is auto-generated for a few architectures, download it from the release portal

• sp3 High Precision Orbits (by IGS)

• rnx2crx is a RINEX compressor (RINEX to Compact RINEX)

• crx2rnx is a CRINEX decompresor (Compact RINEX to RINEX)

• rinex-qc is a library dedicated to RINEX files analysis

• qc-traits declares Traits that are shared between rinex and rinex-qc

• sinex SNX dedicated core library

• ublox-rnx is an application intended to generate RINEX Data from raw uBlox GNSS receiver frames. This application is work in progress at the moment.

Other tools and relevant Ecosystems

• Nyx-space: Navigation, Orbital attitude
• Hifitime: Precise Timing, Timescales, ...
• CGGTTS: Common View Time Transfer

• RTK-RS: Precise Positioning

• GNSS definitions in Rust: GNSS library

Formats & revisions

The core library supports parsing RINEX V4.00 and the current behavior is to fail on higher revisions. NAV V4 is correctly supported as described in the following table.

We support the latest revisions for both IONEX and Clock RINEX.

We support the latest (rev D) SP3 format.

CLI : possibility to load this format in the apps.
CLI + 📈 : possibility to project or extract and plot this format.

Other formats

RINEX-Cli accepts more than RINEX data.

Type	Parser	Writer	CLI	Content	Record Iteration	Timescale
SP3	✔️	🚧 Work in progress	✔️ 📈	High precision SV orbital state	Epoch	GNSS

File formats

Format	File name restrictions	Support

Special Thanks

These tools would not exist without the great libraries written by C. Rabotin, check out his work.

Some features would not exist without the invaluable help of J. Lesouple, through our countless discussions. Check out his PhD manuscript (french)
