Galileo Navigation Data (RINEX v4)

R2026b

For RINEX version 4 files, Galileo navigation data is organized by navigation message type. Each navigation message type may provide ephemeris data, system time offset parameters, Earth orientation parameters, and ionospheric model data, depending on the message.

Galileo navigation messages are returned within the output structure output.Galileo and are grouped by navigation message type.

These Galileo navigation message types are supported:

• data.Galileo.INAV — Integrity Navigation (INAV) messages transmitted on the E1 and E5b signals.

• data.Galileo.FNAV — Frequency Navigation (FNAV) messages transmitted on the E5a signal.

Each navigation message type may include one or more of these message categories:

• Ephemeris navigation messages (EPH), which provide satellite orbit and clock parameters.

• System time offset messages (STO), which provide parameters for transforming between time systems.

• Ionospheric model messages (ION), which provide parameters for ionospheric delay correction.

Detailed descriptions of each Galileo navigation message and its corresponding output format are provided on the message‑specific reference pages:

• data.Galileo.INAV

  • data.Galileo.INAV.EPH — Galileo INAV Ephemeris Navigation Message (RINEX v4)

  • data.Galileo.INAV.STO — Galileo INAV System Time Offset Message (RINEX v4)

  • data.Galileo.INAV.ION — Galileo INAV Ionosphere Message (RINEX v4)

• data.Galileo.FNAV

  • data.Galileo.FNAV.EPH — Galileo FNAV Ephemeris Navigation Message (RINEX v4)

  • data.Galileo.FNAV.STO — Galileo FNAV System Time Offset Message (RINEX v4)

  • data.Galileo.FNAV.ION — Galileo FNAV Ionosphere Message (RINEX v4)
