Abstract: Information integration and network-enable have become the main characteristics of the next generation air traffic management system. In order to guarantee the real-time and precise tracking of global flights, this paper designs the integrated space-air-ground network architecture of global flight tracking based on information integration and sharing, studies the key technology of integrated aeronautical network-enabled information assurance system based on networked authentication, realizes the integrated, interoperable, reliable and efficient air traffic management by using collaborative decision marking(CDM)that supported by system wide information management(SWIM), provides safe, reliable, efficient, and fast operational services, and achieves the goal of global flight tracking based on the integrated space-air-ground network.

Key words: global flight tracking, information integration, operational safety, network-enabled, information security
