RINEX V3

R2026b

RINEX (Receiver Independent Exchange Format) is an international standard for GNSS data exchange. The format defines standard structures for observation, navigation, and related GNSS data, ensuring interoperability across different receivers and processing software.

RINEX files consist of a header section with metadata, and a data section containing epoch-by-epoch or record-by-record data. You can use the rinexread function to extract satellite information from the RINEX files for precise receiver and satellite positioning. You can use the rinexinfo function to get file information, including the file header contents.

RINEX version 3 supports GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS, and NavIC satellite systems.

Navigation and Observation Data Formats

When using the rinexread function to read the navigation or observation data from the RINEX 3 files, the format of the output data structure depends on the satellite system described in the RINEX file. For detailed descriptions of the data structures, see these pages. For example, if your RINEX v3 navigation file provides information about a GPS satellite, the data is stored in data.GPS.

RINEX File Types

The RINEX version 3 standard supports these file types:

  • Observation files

  • Navigation files

  • Meteorological files

Note

The rinexread function currently supports only observation and navigation files.
