The new challenge in propagation channel characterization for non-GSO systems is the large
variability of the atmospheric path length during the satellite contact time, which translates
into large attenuation dynamic range.
he statistical approach used to design the system is
accompanied by the studies to implement and tune the needed Fade Mitigation Techniques
(FMTs), like ACM/VCM, space and time diversity, orbital diversity, etc. In fact, not only
accurate statistical prediction models are needed for the system design (taking into account
the large path when the pointed satellite is low over the horizon), but also channel models
(e.g. time series generators) to verify the system performance and the FMTs design.
Moreover, in order to operate the systems, real time channel assessment techniques must
be studied and developed.
