A Contribution to a Communication Quality Improvement by a Hand Check Survey

The use of different satellite systems in the world has known a large diffusion, not only in the services but in large scale communication networks as it is possible to communicate in any point of the globe. Lately, the communications in the satellite domain have reached a great importance thanks to the Low Earth Orbit (LEO) satellites. This study deals with the main survey of these networks by a demonstration of satellite constellations constitutions and the different interfering factors: the orbit numbers, the satellite numbers in each orbit, the altitude, hence modelling the Hand Check problems.
