Abstract

The invention provides a large-scale low-orbit satellite constellation deployment method, device and equipment and a storage medium. The method comprises the steps of controlling a first group of satellites to enter a nominal orbit to form a first orbit surface after a rocket is separated from a plurality of satellites, controlling the second group of satellites to the Nth group of satellites to stay in a parking orbit, wherein the multiple satellites are divided into N groups, and the height of the nominal orbit is larger than that of the parking orbit, determining the adjustment time of each satellite in the ith group of satellites based on the right ascension difference of the ascending node between the first orbital plane and the ith orbital plane to be formed by the ith group of satellites, wherein the adjustment time comprises the parking time and the climbing time, and based on the parking time, controlling each satellite in the ith group of satellites to stay in a parking orbit, and based on the climbing time, controlling each satellite in the ith group of satellites to climb to a nominal orbit from the parking orbit to form the ith orbit surface so as to form a satellite constellation.

Description

technical field [0001] The present application relates to the technical field of satellite deployment, in particular to a deployment method, device, equipment and storage medium of a large-scale low-orbit satellite constellation. Background technique [0002] In recent years, with the rapid development of satellite technology and the increasing demand for low-earth orbit (LEO) broadband Internet construction, the development of large-scale low-orbit constellations is changing with each passing day. With the development of integrated and automated testing technology, satellite batch manufacturing, rocket recycling and multi-satellite technology have become a reality. LEO satellites are favored because of their low signal transmission delay, small path loss, low cost of orbiting, and wide coverage. Countries attach great importance to the role of large-scale low-orbit constellations in the future. [0003] From the perspective of the development history and trends of low-orbi...
