The development of 6G communication is now putting higher performance requirements on the mobile satellite system. How to achieve comprehensive coverage by adding satellites to mobile communication system has become a popular topic on integrated satellite-ground network. However, using traditional methods to analyze coverage performance is limited by the topology of the satellite constellation. In this paper we use the stochastic geometry to model the LEO constellation. The stochastic geometry analysis method weakens the influence of constellation topology and provides a new representation of the coverage performance characteristics. This paper considers the models of beam coverage angle and atmospheric attenuation on coverage performance and proposes a new interference simplification method. It provides a new tool for the future optimization analysis of coverage performance of LEO satellite constellation and gives a new general expression for the coverage probability. The simulation shows that the coverage analysis model established in this paper can clearly represent the characteristics of the variation of the coverage probability with different parameters, which is conforms to the changing trends of the actual satellite constellation. For example, it can obtain the number of satellites with optimal coverage probability at different orbital altitudes.
