There are many LEO satellite constellation plans in China, and resource integration is the trend. At present, these three major projects are all in suspension. It is a great challenge to establish a constellation system of low-orbit satellites in China to deal with the hooliganism of the United States, and to find a feasible model. This is also the core interest of China, which has important strategic value and can save resources and reduce costs to the greatest extent.
Hongyan Project: It is planned to launch 80 small satellites to build China's first low-orbit narrow-band communication satellite constellation, and finally build a space-based Internet of Things covering the whole world.
