Building China into a cyberpower and digital country urgently needs to get rid of the network sovereignty heteronomy situation

and construct independent and efficient satellite communication network

which integrated with the ground communication network. Based on Tsien Hsueshen's system engineering theory

China Aerospace Academy of Systems Science and Engineering put forward the concept and technological framework of "Integrated Satellite Networks"

aiming to provide a comprehensive guarantee for the cyberpower. In this paper

the strategic significance

characteristics

main goals of Integrated Satellite Networks and the main problems faced are analyzed. On this basis

the preliminary conception and general framework of the network structure is put forward

and the key technology and the way to achieve it is studied.
