BeiDou Navigation Data (RINEX v3)

R2026b

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

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

`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)
`omega`	`double`	Argument of perigee (rad)
`OMEGA_DOT`	`double`	Reference rate of right ascension (rad/s)
`IDOT`	`double`	Rate of inclination angle (rad/s)
`BRDCOrbit5Spare2`	`double`	Spare entry. May be used in a future version.
`BDTWeek`	`double`	BDT week number, with Toe. Continuous number counted from the BeiDou Time epoch (1 January 2006).
