摘要：The next-generation air traffic control system has advanced in a way that directs safely as many aircraft as possible in the limited airspace to meet rapidly increasing demands for air traffic. PBN is a navigation method recently released by ICAO to combine RNAV and RNP. As airspace capacity increased owing to the relaxation of the aircraft separation standards and the shortest routes between fixed points (or waypoints) that aircraft pass through were connected, the general flight distance and time have been reduced. PBN requires accuracy in the measurement of aircraft positions and flight route calculation for effective air traffic control. ADS-B sensor is a core component of PBN. ADS-B sensor data generated based on the GPS, the accurate information on the aircraft include a like position, altitude and direction, the generated data and transmits to the ground. In the existing air traffic control system, the position of the aircraft, which is measured by PSR has a lot of errors. Therefore, it has allowed a significant error rate in distance measurement and RAM centered on the aircraft to use the position of the aircraft. Fusion track data to be used in the next-generation air traffic control system utilizes the track data that combines PSR track and ADS-B sensor data, it can calculate the accurate position of the aircraft. In this paper, I proposed the accurate aircraft the distance measuring method and applying the measured result in the RAM using the fusion data track. First, for accurate position measurement and monitoring of aircraft on an allocated route, a virtual aircraft position on a route is mapped in reference to rectangular coordinates with straight lines and aircraft position. Second, the distance between two points is calculated by means of a Vincenty formula algorithm, and the calculation result is utilized for aircraft conformance monitoring. When the method proposed in this paper is applied, it is possible to reduce the separation gap of an aircraft for more accurate aircraft position measurement, and a safe navigation of aircraft as much as possible in the limited airspace is guaranteed. Also proposed a method for secure transmitting aircraft safety information to a controller or an external system using a physical unidirectional transmission method.
