QZSS Navigation Data (RINEX v3)

R2026b

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

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

Field	Data Type	Description
`Time`	`datetime`	QZSS clock time
`SatelliteID`	`double`	Satellite system (J) Satellite PRN-192
`SVClockBias`	`double`	SV clock bias (s)
`SVClockDrift`	`double`	SV clock drift (s/s)
`SVClockDriftRate`	`double`	SV clock drift rate (s/s², equivalent to 1/s)
`IODE`	`double`	Issue number of the satellite ephemeris data set, Issue of Data, Ephemeris (IODE)
`Crs`	`double`	Amplitude of the sine harmonic correction term to the orbit radius (m)
`Delta_n`	`double`	Mean motion difference from the computed value at reference time (rad/s)
`M0`	`double`	Mean anomaly at the reference time (rad)
`Cuc`	`double`	Amplitude of the cosine harmonic correction term to the argument of latitude (rad)
`Eccentricity`	`double`	Eccentricity of the satellite orbit (dimensionless)
`Cus`	`double`	Amplitude of the sine harmonic correction term to the argument of latitude (rad)
`sqrtA`	`double`	Square root of the semimajor axis (`sqrt(m)`)
`Toe`	`double`	Time of ephemeris (s of respective satellite week)
`Cic`	`double`	Amplitude of the cosine harmonic correction term to the angle of inclination (rad)
`OMEGA0`	`double`	Longitude of ascending node of orbit plane at weekly epoch (rad)
`Cis`	`double`	Amplitude of the sine harmonic correction term to the angle of inclination (rad)
`i0`	`double`	Inclination angle at reference time (rad)
`Crc`	`double`	Amplitude of the cosine harmonic correction term to the orbit radius (m)

`IDOT`	`double`	Rate of inclination angle (rad/s)
`L2ChannelCodes`	`double`	Codes on L2 channel
`GPSWeek`	`double`	GPS week number, with `Toe`. Continuous number, not `mod(1024)`. QZSS System Time (QZSST) is aligned to GPS time and uses the same epoch and week numbering.
`L2PDataFlag`	`double`	L2P data flag
`SVAccuracy`	`double`	SV accuracy (m), derived from the user range accuracy (URA) index. See GPS ICD Section 20.3.3.3.1.3.
`SVHealth`	`double`	SV health, 6 bits (subframe 1, word 3, bits 17–22) as defined in the GPS ICD.
`TGD`	`double`	Timing group delay (s)
`IODC`	`double`	Issue number of the satellite clock data set, Issue of Data, Clock (IODC). (See GPS ICD Section 20.3.3.3.1.5)
`TransmissionTime`	`double`	Transmission time of the message (seconds of the GPS week)
`FitInterval`	`double`	Fit interval (h). Derived from subframe 2, word 10, bit 17 together with IODC. See Table 20-XII of the GPS ICD.
`BRDCOrbit7Spare3`	`double`	Spare entry. May be used in a future version.
`BRDCOrbit7Spare4`	`double`	Spare entry. May be used in a future version.
