The Rician statistics depend on the carrier frequency, as well as on the geometry of the Sun, Earth and Probe, i.e., the SEP angle shown in Fig. 15. Usually, the Rician fading distribution is specified in terms of the scintillation index, noted by m, which is the ratio of the standard deviation of the received signal power to its mean. This topic has been recently investigated in the context of a research project funded by the ESA. Several solutions have been proposed for this scenario in [181], [182] and [183].

N2 - Satellite communications (SatComs) have recently entered a period of renewed interest motivated by technological advances and nurtured through private investment and ventures. The present survey aims at capturing the state of the art in SatComs, while highlighting the most promising open research topics. Firstly, the main innovation drivers are motivated, such as new constellation types, on-board processing capabilities, non-terrestrial networks and space-based data collection/processing. Secondly, the most promising applications are described, i.e., 5G integration, space communications, Earth observation, aeronautical and maritime tracking and communication. Subsequently, an in-depth literature review is provided across five axes: i) system aspects, ii) air interface, iii) medium access, iv) networking, v) testbeds prototyping. Finally, a number of future challenges and the respective open research topics are described.
