style="text-indent:2em;">Satellite application refers to the application of the achievements of satellite technology and the developed space resources in economic construction, national security, scientific and technological development, social progress and many other aspects. Satellite application is the whole part of the satellite industry chain. According to technical fields and service methods, satellite applications currently mainly include satellite communications, satellite navigation and satellite remote sensing.

The upstream satellite network layout drives the development of the downstream application industry

The satellite application industry is a national strategic high-tech industry. The development and production of applied satellites has formed a series, and is transforming from an experimental application type to a business service type. Satellite application has become an important support for economic construction, social development and government decision-making.

After years of development, my country has formed a very complete satellite industry chain. The industrial chain of China's communications satellite industry is divided into three segments:

· The upstream enterprises in the industry chain mainly involve satellite manufacturing, satellite launch, satellite ground equipment and network construction enterprises;

· The participants in the midstream of the industry chain are satellite service operators;

· The downstream industry chain involves multiple fields of business, mainly including: mass consumer communication services, satellite fixed communication services and satellite mobile communication services.
