- Fast
- Open sources: read and access all the code!
- All modern GNSS constellations, codes and signals
- Surveying with GPS, Galileo, BeiDou and QZSS
- Time scales: GPST, QZSST, BDT, GST, UTC, TAI
- RINEX V4 full support
- Efficient seamless compression and decompression
- Most RINEX formats supported (see following table)
- High Precision Clock RINEX products (for PPP)
- DORIS (special RINEX)
- Many pre-processing algorithms including Filter Designer
- Several file operations: merging, splitting, time binning (batch)
- Navigation is currently not feasible with Glonass and IRNSS
- File production might lack some features, mostly because we're currently focused on data processing

The parser supports RINEX V4.0, that includes RINEX V4 Navigation files.
We support the latest revisions for both IONEX and Clock RINEX.
We support the latest (rev D) SP3 format.
