Ionospheric delay gradient at Bangkok station (KMIG)
The ionospheric delay gradient (mm/km) is the spatial rate of change in the ionospheric path delay. It represents how much the ionospheric error differs over a horizontal distance between the GNSS ground station and the aircraft (or user receiver).
