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), and NovAtel OEM binary logs (RANGE and the compressed RANGECMP). 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).
