The Research Of New Aeronautical Telecommunication Network Technology

Since the late nineteen century, human beings have achieved tremendously in Electronic Communication Technology with the advancement of society and the development of technology. From the applications of Close-range Corded Telephones and Manual Morse Telegraphs to the High-level Intelligent Terminals, Super Computers, and the Optic Fibers, Satellite Communications. The innovation of Electronic Communication Technology has made our life and work more efficient and easier.The Aeronautical Telecommunication, which is the Electronic Communication Technology applied in Aeronautical Communication, is the most important fundamental technology to ensure the aviation flights safe, normal and highly efficient. At the same time, the rapid development of aviation business puts higher requirements to the Aeronautical Telecommunication in Air Traffic Management, Airline Company Navigational Fairs Management, and the Aviation Operation Administration Management. The International Civil Aviation Organization (ICAO) had paid highly attention to this matter. Since the early 1980s, ICAO had organized experts to research on new technology in order that the new CNS, ATM and ATN System can be used in the field of International Civil Aviation. The new ATN which can be researched and developed will build a solid base for improving safety and efficiency in civil aviation.The new Aeronautical Telecommunication Network is based on a global digital communication network and protocol. ATN is mainly used in the transmission and exchange of the aviation activity and plan between the units of air traffic services as well as the handover and coordination of air traffic services. It is an important component of the CNS/ATM system and is a complete solution of the new Aeronautical Telecommunication System.This dissertation emphasizes on discussion of the basic concept, system structure and composing principle of ATN as well as the transmission type of network, and expounds the key technologies including the issuance and computing of Router, the Transport Layer Gateway, the analysis of data computing, the inosculation with the IP technology, etc. On the basis of the abovementioned, it explains that the new ATN is a tridimensional aeronautical data network which can better satisfied the requirements of the increasing aeronautical telecommunication business. The dissertation also probes into the technology of the transition from AFTN to ATN in present moment, and at length looks toward the developing prospect of ATN.
