11611 自動従属監視(ADS-C)データ解析(各種システムの安全性(2),OS.10 各種システムの安全性)

The conventional surveillance of aircraft flying on the oceanic routes, HF communication, is making the transition to Automatic Dependent Surveillance (ADS-C). In the environment of ADS-C, Air Traffic Control (ATC) authorities use the position information transmitted from the onboard system of aircraft automatically. In order to estimate the collision risk of aircraft flying on the oceanic routes quantitatively, we are analyzing the ADS messages transmitted from aircraft and ATC. In this paper, we introduce the methodology of analysis and its results.
