Providing truly ubiquitous connectivity requires development of low Earthorbit (LEO) satellite Internet, whose theoretical study is lagging behindnetwork-specific simulations. In this paper, we derive analytical expressionsfor the downlink coverage probability and average data rate of a massiveinclined LEO constellation in terms of total interference power's Laplacetransform in the presence of fading and shadowing, ergo presenting a stochasticgeometry based analysis. We assume the desired link to experience Nakagami mfading, which serves to represent different fading scenarios by varying integerm, while the interfering channels can follow any fading model without an effecton analytical tractability. To take into account the inherent nonuniformdistribution of satellites across different latitudes, we model the LEO networkas a nonhomogeneous Poisson point process with its intensity being a functionof satellites' actual distribution in terms of constellation size, the altitudeof the constellation, and the inclination of orbital planes. From the numericalresults, we observe optimum points for both the constellation altitude and thenumber of orthogonal frequency channels; interestingly, the optimum user'slatitude is greater than the inclination angle due to the presence of fewerinterfering satellites. Overall, the presented study facilitates generalstochastic evaluation and planning of satellite Internet constellations withoutspecific orbital simulations or tracking data on satellites' exact positions inspace.
