GPS Navigation Data (RINEX v3)

R2026b

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

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

`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)

`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)
