Abstract: Nowadays, there is an increasing demand for the use of satellites for communications.This is because satellites are able to cover large geographical areas and reach places where other traditional communication systems cannot reach. Satellite communications are usually done through the so-called geostationary orbit satellites (GNSO or "Geo-Stationary Orbit Satellites") however the increased demand mentioned above is changing the sector and is causing non-geostationary orbit satellites (NGSO or "Non-Geo-Stationary Orbit Satellites") located in lower orbits and that have been commonly used for global positioning and scientific exploration, as well as for capturing high-resolution images of the Earth's surface, are transforming their uses and are beginning to be used for communication purposes. The purpose of this work is to perform a comparative analysis of the different rain attenuation estimation models for satellites at different frequencies and elevations to be afterwards compared with the standardized ITU-R model. This is essential when facing changes in the industry since, as telecommunication professionals know, the most damaging phenomenon for satellite communications is rain attenuation. This phenomenon is more damaging as the wavelength approaches the size of a drop of water, i.e. the higher the frequency of the emitted wave.
Keywords: effects of rain
