Ray Tracing through Realistic Ionosphere
eXplorer (RayTRIX) collection contains traces of remote high
frequency signal propagating through E, F1, and F2 layers of
the ionosphere for a given arbitrary time and radio link with
one transmitter and one receiver. Also computed are values of
the Maximum Usable Frequency (MUF) for each layer, defined as
the maximum frequency at which communication between the end
points of the given radio link is still possible. RayTRIX
computes signal flight time (dependent variable) as a
function of the operating frequency (independent
variable). Computation is done using an analytical solution
of the signal propagation through a plasma layer of the
quasi-parabolic (QP) shape. RayTRIX-Composite
Quasi-Parabolic (CQP) represents the
ionospheric channel as a composite of three QP descriptions
for E, F1, and F2 layers at the mid point of the given radio
link. The CQP plasma density profile is built by fitting QPs
to the IRTAM assimilative model of the real-time ionospheric
weather, available via GAMBIT database portal at
