RINEX converter & editor
Turn a raw receiver log (u-blox, Septentrio, NovAtel, Trimble, BINEX), an RTCM3 capture, or an existing RINEX/CRINEX file into the RINEX you need — everything runs in your browser and nothing is uploaded.
- Decode receiver / RTCM3 logs → RINEX observations + navigation
- Convert RINEX between 2.11, 3.04 and 4.01
- Compress / decompress Hatanaka (CRINEX)
- Edit header fields (marker, antenna, receiver, position…)
- Decimate, subset by system/PRN/signal, or crop by time
- Splice / merge several files, or split the output by interval
- Inspect any file record-by-record, field by field
- Hand off to the QC page for full quality analysis

u-blox UBX (RXM-RAWX) · Septentrio SBF (Meas3 / MeasEpoch) · NovAtel RANGE / RANGECMP · RINEX & Hatanaka (CRINEX) obs — gzipped files welcome. Drop several to splice/merge them into one file. Everything runs in your browser; the file never leaves your machine.
Frequently Asked Questions
- Which receiver formats can be converted to RINEX?
- u-blox UBX raw logs (RXM-RAWX, e.g. from a ZED-F9P), Septentrio SBF files (both the compressed Meas3 blocks and classic MeasEpoch), NovAtel OEM binary logs (RANGE and the compressed RANGECMP), Trimble RT17/RT27, BINEX, and RTCM3 logs (e.g. a recorded NTRIP stream) — decoded by the same engine as the live Stream Inspector. Gzipped files are accepted; the format is detected from the frame structure, not the file name.
- Does my file get uploaded anywhere?
- No. The decoding and RINEX writing run entirely in your browser — the file never leaves your machine.
- Which RINEX versions can be produced?
- RINEX 3.04, RINEX 4.01 and RINEX 2.11 observation files, gzip-compressed. For RINEX 2, modern signal codes are mapped onto the version 2 observation types.
- How accurate is the conversion?
- The decoders are validated observable-for-observable against RTKLIB conversions of reference datasets — pseudoranges, carrier phases, Doppler and C/N0 agree to the RINEX printing precision (0.5 mm / 0.0005 units).
- Can I just see what is inside a file, without converting?
- Yes. Every file opens a record census — each message/block type and how many of each — and each type expands into a field-by-field inspector with a hex view. This works for any receiver file, including navigation- or almanac-only logs that carry no observations at all.
