Ionosphere function

WebThe mapping function is crucial for the conversion of slant total electron content (TEC) to vertical TEC for low Earth orbit (LEO) satellite-based observations. Instead of collapsing the ionosphere into one single shell in commonly used mapping models, we defined a new mapping function assuming the vertical ionospheric distribution as an exponential … WebSince the characteristics of ionosphere varies with time, the channel is time varying. The propagation path has different dielectric constants functions of space coordinates, so the medium is inhomogeneous. The dielectric constant and refractive index are functions of time derivative (or frequency) so the channel is frequency dispersive.
