An Evaluation Process of ADS-B Message and Statistical Evaluation

抄録

Currently, Automatic Dependent Surveillance-Broadcast (ADS-B) is used as one of the aircraft surveillance systems in Europe, the United States, and other regions. ADS-B messages are transmitted from transponders loaded on aircraft, which include position, altitude, velocity, and other operational information. The implemented information provides positional performance indexes of the Navigation Integrity Category (NIC) and Navigation Accuracy Category-Position (NACp). NIC and NACp values are required to meet operational performance to use ADS-B for aircraft surveillance. We installed an ADS-B receiver near Sendai airport to evaluate quality of ADS-B performance and developed analytical tool for them. This paper discusses our method for processing ADS-B data to estimate quality of ADS-B performance. Using our evaluation concept, statistical results of NIC and NACp are evaluated.
