Ionospheric Perturbations

While "normal" ionospheric conditions have little influence on most applications using trans-ionospheric radiolinks, disturbed conditions are a challenge for many. Ionospheric perturbations cause signal degradation and even loss of signal which in turn causes a degradation of system functionality and failures. Measures of ionospheric perturbations provided here are scintillations, rate of change of TEC index (ROTI) and equivalent slab thickness.
