| Mega Satellite Constellations are the latest achievement of the new space age. This technology, with a large number of satellites, at a low orbital altitude, provides the possibility of providing services with high bandwidth, low delay and competitive with other terrestrial communication platforms. One of the important requirements in establishing reliable and stable communication in satellite communication is the study of the propagation of radio waves in different frequency bands in order to extract parameters effective in the efficiency of the satellite link and creating a suitable model for predicting the effects of factors affecting wave propagation based on the parameters obtained for different regions. In this paper, in addition to a brief review of the key features of satellite constellations, as well as a more detailed review of an example of this type of new space technology, the issue of atmospheric phenomena affecting the propagation of satellite waves at Ku and Ka frequencies has been investigated. In this study, not only LEO orbit, but also the earth’s GEO various atmospheric phenomena and their effects on the satellite signal quality are described Also, in accordance with the introduced methods, a proposed arrangement sample for simultaneous measurement of satellite signal and meteorological parameters has been presented and operational measurement results have also been presented. |
