WebGPS users with single-frequency receivers need ionospheric electron content information in order to achieve positioning accuracy similar to dual-frequency receivers. The GDGPS System provides a global real-time maps of ionospheric electron content (currently producing a map every 5 minutes). WebThe ionosphere is a dispersive medium for GPS signals (f1 = 1575.42 MHz and f2 = 1227.60 MHz) in the microwave band. Therefore, signals traveling through this medium are affected proportionally to the inverse of the square of their frequencies. This effect can reveal information about the parameters of the ionosphere in terms of the TEC of a ...
