Abstract

Abstract: In recent years，with the rapid development of satellite technology and the increasing demand for low earth orbit（LEO）satellite broadband internet construction，the development of LEO large-scale constellations is changing rapidly.Aiming at the initial deployment of Starlink constellation，firstly，the current status of the Starlink constellation was discussed，and the altitude changes of orbiting satellites were analysed.Then，the deployment of the Starlink constellation was briefly analyzed from two aspects by utilizing the public two-line element（TLE），including satellite being launched into orbit and orbital plane distribution，and the changing rule of ascending node was given.At the same time，the ground coverage performance of the Starlink constellation was simulated and analyzed.Finally，the constellation orbital planes and phase distribution，handling of the faulty satellites，and the number of visible satellites were obtained.The results of the analysis are expected to provide reference for China′s future deployment of large-scale LEO constellations.

Key words: , LEO constellation；satellite broadband internet；two-line element；constellation deployment；ground converge
