Galileo Navigation Data (RINEX v3)

R2026b

This table shows the format of the Galileo navigation data field Galileo for RINEX version 3 returned in the output argument data from the rinexread function.

If the navigation data contains Galileo data, it is returned in the field data.Galileo.

DataSources

double

Bitmask identifying the Galileo navigation message sources used to populate the navigation parameters and the signal pair to which clock and accuracy parameters apply.

Navigation message source bits:

  • Bit 0 — Data derived from I/NAV broadcast on E1‑B

  • Bit 1 — Data derived from F/NAV broadcast on E5a‑I

  • Bit 2 — Data derived from I/NAV broadcast on E5b‑I

Bits 0 and 2 may both be set if INAV messages were merged. Bit 1 (F/NAV) is not set together with bits 0 or 2 (I/NAV), because I/NAV and F/NAV are decoded into separate ephemeris records.

  • Bit 3 reserved for Galileo internal use

  • Bit 4 reserved for Galileo internal use

Clock and accuracy source bits:

  • Bit 8 — Clock (af0–af2), Toc, and SISA apply to E5a–E1

  • Bit 9 — Clock (af0–af2), Toc, and SISA apply to E5b–E1

Bits 8 and 9 are mutually exclusive.

GALWeek double GAL week number, with Toe. Continuous number (not rolled over).
BRDCOrbit5Spare4 double Spare entry. May be used in a future version.
SISAccuracy double Signal in space accuracy (m). A value of -1.0 indicates that there is no accuracy prediction available (NAPA) or the accuracy is unknown.

SVHealth

double

SV health (See Galileo ICD Section 5.1.9.3):

  • Bit 0 — E1B DVS

  • Bits 1-2 — E1B HS

  • Bit 3 — E5a DVS

  • Bits 4-5 — E5a HS

  • Bit 6 — E5b DVS

  • Bits 7-8 — E5b HS

BGDE5aE1

double Broadcast group delay between the Galileo E5a signal and the E1 signal (s)

BGDE5bE1

double Broadcast group delay between the Galileo E5b signal and the E1 signal (s)

TransmissionTime

double

Transmission time of the message (seconds of the Galileo System Time week)

BRDCOrbit7Spare2 double Spare entry. May be used in a future version.

BRDCOrbit7Spare3

double Spare entry. May be used in a future version.

BRDCOrbit7Spare4

double Spare entry. May be used in a future version.
