Discussion and Research of Aviation Data Link Based on ADS

Abstract

With the rapid development of the global aviation industry, air traffic flow has increased dramatically. In order to ensure the safe and orderly operation of air traffic, higher requirements are put forward for air traffic control and surveillance technology. This paper introduces ADS system which is widely used at present, briefly analyses its research status, communication channels and networking protocols used at the present stage, gives the typical application scenarios of the system, analyses the data integrity and security problems that restrict the development of ADS-B, and finally forecasts the future development direction of ADS-B, including ATN, FANS and BDS. Positioning and satellite-based ADS-B system.
