![]() ![]() In this tutorial, we discuss a recently proposed mathematical framework that enables tractable analysis of LEO satellite-enabled communication systems while capturing the influence of satellites’ numbers and altitudes and the spatial distribution of earth stations. Due to the fundamental difference between these novel communication systems, especially the spatial distribution of the communication nodes, and the typical terrestrial communication networks, we need to think of creative techniques to analyze such communication systems mathematically. Given that we have multiple competing companies launching various constellations with diverse altitudes and numbers of satellites, we can envision a set of spheres concentric with the earth with large numbers of LEO satellites distributed on the surfaces of each of these spheres. The main driver to achieving such satellite-based global connectivity is deploying large numbers of LEO satellites at a set of altitudes, ranging from 300 km to 1500 km, to ensure that every part of the earth will be covered by at least one satellite at all times. One key application is providing internet broadband services to people everywhere around the globe, which is considered a significant step towards resolving the digital divide problem. The significant technological advances in the low earth orbit (LEO) satellites industry have opened the door to a new realm of LEO-based applications. We are witnessing an unprecedented boost in the space industry. ![]()
