Analysis of Characteristics and Requirements of Large LEO Constellations Management

With the rapid development of micro-satellite technology, the significant reduction in the cost of mass satellite production, and the rapid growth of application demand in the fields of global communication, navigation and remote sensing, large LEO constellations with the advantages of global seamless coverage, low transmission delay, high transmission rate, large information capacity, and individual satellite failures do not affect overall performance have become a major hot spot at present and for quite a long time in the future. As a basic support for constellation construction and effectiveness, how to manage a large constellation stably and efficiently has become a practical problem that needs to be solved urgently. Briefly introduced the development of large constellations domestic and abroad, sorted out and summarized characteristics of management and challenges faced in long-term operation compared to single satellite or small constellations, analyzed and proposed management requirements such as automation and intelligence, health management, configuration maintenance, and autonomous operation. Research results can be used as a reference for the development and construction of large constellation management systems.
