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.
