항공관제시스템을 구성하는 하부 시스템중 하나인 감시자료처리시스템(SDP, Surveillance Data Processor)은 항공 감시 레이더 등 다양한 감시 센서로부터 감시자료를 전달 받아 항공기의 항적을 추적하는 시스템으로서, SDP의 항적 추적 성능은 항공기의 안전 운항에 직접적인 영향을 미친다. 따라서 개발과정에서 SDP의 요구 성능에 대한 검증은 필수적이며, 특히 대표적인 다중 센서 다중 타겟 추적(Multi-Sensor Multi-Target Tracking)시스템으로서 다양한 타겟 추적 방법이 존재함에 따라 정량적인 추적 정확도 성능 평가가 중요하게 여겨지고 있다. 본 연구에서는 현재 한국항공우주연구원에서 개발 중인 SDP의 항적 추적 성능검증을 위한 요구 성능 정의, 테스트 환경 구축, 테스트 결과에 대해 정리하였다. As a sub-system of an air traffic control system, SDP(Surveillance Data Processor) provides with the system tracks of aircraft using the surveillance sensor data from various air traffic surveillance sensors, such as radars. Therefore, the high accuracy of tracking results is a crucial requirement for safe flights, and verification of the required system performance of SDP is an essential step in development. Moreover, the quantitative evaluation of target tracking accuracy is important for newly developed SDP, since there are several tracking methods for Multi-Sensor Multi-Target Tracking, such as MRT(Multi Radar Tracking), inevitably required as the main function of SDP. In this study, definition of required system performances, establishment of test environment, and test results for MRT performance evaluation of SDP, which is being developed in KARI(Korea Airspace Research Institute) are presented.

본 논문은 미래 항공교통관리(Air Traffic Management, ATM)의 핵심개념으로 받아들여 지고 있는 궤적기반운용(Trajectory-based Operations, TBO)에 대한 기술동향을 담고 있다. ICAO(International Civil Aviation Organization)가 발표한 ASBU(Aviation System Block Upgrade)에 기술된 TBO 운용개념을 살펴보고, 미국과 유럽에서 각각 진행 되어온 궤적기반운용에 대한 운용개념 수립과 관련 연구개발 사례들을 통해 근 미래에 실현 가능한 운용개념 및 절차를 구체화하였다. 운용개념 정리를 통해 파악된 요소기술들(technical enablers)을 간단히 소개하며, 관련된 연구개발 진행 현황을 정리하였다. The research and development trend of Trajectory-based Operations(TBO), which is considered as a key concept of future Air Traffic Management(ATM), is presented in this paper. The operational concepts of TBO in ASBU(Aviation System Block Upgrade) from ICAO(International Civil Aviation Organization) have been summarized, and the detailed operational concepts and procedures, which can be realized in the near future, are described through the investigations of operational concept development and related research/development activities of TBO in USA and Europe. The technical enablers, which have been identified based on understanding of TBO operational concepts, are introduced, and related research/development status of each technical enabler has been presented.

Four dimensional(4-D) trajectory modeling is conducted based on flight plan. The flight plan is divided into several segments which represent certain operating flight modes. Thrust, drag and fuel consumption rate of an aircraft are calculated using BADA provided by Eurocontrol. The trajectory is modeled with the rate of climb/descent calculated with Total-Energy Equation. The simulation results with a typical aircraft and its flight plan indicate that the trajectory modeled corresponds well with the suggested flight plan. The performance profiles including total endurance time and time history for speed, thrust, drag and fuel consumption were also appropriately generated.

Estimation of the taxi-out and taxi-in times of aircraft on a airport surface is one of the essential features of Departure Manager (DMAN). Especially for an airport with multiple runways and large ramp areas, estimation of the taxi-out and taxi-in times are mainly dependent on the taxi routes on airport surface. This paper described the method of automatic extraction of the the taxi routes using the ASDE track data and the Dijkstra algorithm based on the node-link model of a airport surface movements. In addition, we analyzed the ground operation status of Incheon International Airport using the extracted taxi routes.
