RayTRIX: Analytical raytracing through CQP vertical Ne profile at the radiolink midpoint

Given the Composite Quasi-Parabolic (CQP) represenration of the vertical profile of electron density in the ionosphere at the midpoint of a radio link, this Computation uses analytical ray tracing to derive traces of radio signals propagating through the ionospheric channel, with up to 3 layers and two propagation modes per layer (for the lower and upper (Pedersen) zenith angle of the ray).
