Analyses of Qianfan constellation coverage with respect to the ground users as of May 23, 2025

Overview
The Qianfan constellation has been proposed by joint task teams in Shanghai, China, which has been under development. Its goal is to form a constellation of more than 10, 000 microsatellites, which is dedicated to providing space-based internet services. Based on an open data set of orbit information online, authors have made simulations of the Qianfan constellation, consisting temporarily of 90 microsatellites. Semi-major axis, inclination, and eccentricity data analyses are made, which have shown the status quo of 90 satellites in orbit. 10 deg *10 deg grids are assumed on the surface of the Earth; 90-satellite coverage has been simulated with respect to the assumed ground grids. These simulations and analyses will help technicians learn the current state of the Qianfan constellation, and further promote the effective development of the follow-up Qianfan satellites.
