Ionospheric scintillation is the random fluctuation of radio wave amplitude and/or phase when traversing ionospheric plasma irregularity structures. It impacts a wide range of space‐based applications, including Global Navigation Satellite Systems (GNSS), and it occurs most frequently and has the strongest effects in the equatorial region 1 ...Cited by: 2

Abstract: With the advent of satellite communications systems at frequencies varying from \sim140 MHz to 1600 MHz as well as navigation and ranging systems in the 1200-1600 MHz portions of the spectrum, the effect of equatorial irregularities on fading signals has become of importance. Recent observations of the signal statistics of scintillations at frequencies ranging from 136 MHz to 6 GHz ...Cited by: 91

May 01, 2019 · It is a regional, short-time forecast system to support research and users of space-based communication and navigation systems (Groves et al., 1997). Its purpose is to aid the prediction of ionospheric scintillation-induced degradations on communication satellites’ signals in the equatorial region, with the overall aim of developing mitigating strategies to reduce the impact of such degradations on systems.Author: A.O.
