Abstract: LEO interconnected satellite system is considered to be the latest and most promising satellite communication system, which can meet practical needs of global meteorological data and product transmission, meteorological mobile communication and space-based meteorological load detection to some extent. And with broad application prospects, it supports the implementation of the global monitor, forecast and service. Through the study of the development history of domestic and foreign low orbit interconnected satellite system, we first analyzed the industrial chain, risks and the demands in meteorological application of LEO, and then put forward some suggestions to speed up the application and popularization in the field of meteorology through commercial cooperation.
