Research On The ADS-B Message Processing And Displaying System Based On SuperMap Platform

As the number of the aircraft in the airspace is increasing, people pay moreattention on the flight safety problem. Automatic dependent surveillance broadcastsystem (ADS-B) is a new generation air traffic control system. It provides lots offunctions for the aircraft like automatic recognition, collision avoidance, pathprediction and so on. It provides strong protection for the aircraft flight safety.Combining the information of GIS system SuperMap, we can make thegeographic information and ADS-B message integrated. After the displaying andprocessing with the visualization interface system, user can observe the surroundingairspace easily and receive the information of surrounding terrain and aircraft. Itmakes the display information more rich and clear.This paper researches the use of the SuperMap component of GIS system in thissystem, including the data structure and processing methods. After analyzing thesystem function and information structure of the ADS-B system, this paper discussesthe analysis and processing on the ADS-B system message based on1090ES chain.At last this paper discusses and researches on the software which uses the SuperMapplatform to display and process the ADS-B message. The functions include dataframe analysis, trace drawing and some auxiliary applications.
