Automatic Dependent Surveillance Broadcast (ADS-B) technology had the advantages of high monitoring accuracy, fast refresh, low cost and simple maintenance. It was favored by civil aviation air traffic control departments and was often used in route surveillance services. As an important parameter of ADS-B, the horizontal position uncertainty of ADS-B reflected the level accuracy of target positioning. In this paper, the horizontal position uncertainty of DO-260 version was analyzed, and the correctness of position errors of different levels of horizontal accuracy was verified. Based on the probabilistic and statistical characteristics of position error, the collision risks such as target conflict and danger proximity under current ADS-B operating interval were evaluated, which provided a theoretical basis for flight interval assessment under ADS-B control.

Key words: automatic dependent surveillance, horizontal position uncertainty, collision risk, air traffic control
