International Civil Aviation Organization adopted the program to improve performance of aviation-related data systems through the ASBU for 20 years from 2013. Research and development for integrated management network of aeronautical telecommunication data through SWIM(System Wide Information Management) technology which is part of program, are being progressed in the United States and European countries. Therefore, in this paper, we suggest a method of testbed implementation based on technology of aeronautical data services architecture applied the concept of SOA(Service Oriented Architecture), development of future data management model for integrated management of aeronautical data, and development of user-centric integrated aeronautical data management network through adapter technology for interoperating legacy aeronautical data system to develop even technology with development trends of advanced countries.

Development of air navigation and avionics technologies led to solve the problems that conventional ATM system had. The International Civil Aviation Organization developed the Aviation System Block Upgrades (ASBU) initiative in order to harmonize global ATM planning and technology upgrades and urged to implement the recommendations for the member States. The ASBUs provide the road map to assist air navigation service providers in the development of their individual strategic plans and investment decisions. In this paper, the operational concepts in 2 performance improvement areas, Airport Operations and Globally Interoperable System and Data in ASBUs, have been summarized. In Airport Operations area the new management technologies and required systems are presented for optimizing the traffic flow in airport area and terminal airspace. Data format standards and required systems presented for information integration and usage of the new system under Globally Interoperable System and Data area.

점증하는 항공교통량의 원활한 수용과 안전한 항공기술 저변확대를 위하여 ICAO는 성능기반의 항공교통관리(ATM) 체계와 시스템을 Upgrade할 구체적 이행계획인 ASBU를 개정하고 체약국들의 수용을 촉구하고 있고, 우리나라는 ICAO의 5연임 이사국으로서 ASBU의 주요 Module에 대응하는 모든 Working Paper에 대하여 적극 수용한다는 입장이다. 본 논문은 ASBU의 PIA 4에 해당하는 CDO 및 관련 Module인 TBO의 개념을 살펴보고, 선도적으로 운용되고 있는 사례를 분석해 봄으로써 미래에 대응하는 방안을 찾고자 하였다. CDO는 새로운 장비와 시스템을 갖추지 않더라도 절차의 보완으로 개선할 수 있는 부문에 속하므로 우리나라의 운영 현황을 리뷰하고 그 영향에 대하여 정리해 보았다. 다만, 항공기 고도 강하 단계에서의 개선효과가 상승 또는 순항 단계에 비하여 효율성이 상대적으로 미미한 편이고, ATM 구분 상 기상 등의 외부 변수에 취약하여 효율성 연구에 접근하기 어려운 면이 있으나, 고밀도 공항의 특화된 CDO 기법 개발을 통하여 연료절감 및 탄소배출량 저감, 소음감소의 성과를 이룬 선진 사례를 들어 국내에 적용할 수 있는 방안에 대하여 장기적으로 연구하고자 한다.

It is necessary to reduce aviation GHG(CO2) emission to ensure aviation sustainable development. Operational improvements may not contribute significantly to carbon reduction but it can sustatially reduce emission in a short term. ICAO has developed GANP and ASBU to optimize operations and countries are making efforts to expand infrastructure and develop technology. The legal barriers to operational improvement are based on the notion of state sovereignty under the Chicago Convention which allows countries to control inefficiencies based on borders or limit or prohibit the passage of aircraft. Chicago Convention does not grant unlimited freedom of air sovereignty and if the concept of state sovereignty is interpreted according to the times it is possible to achieve smooth operational improvement.

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.

항공기는 공중에서 양력을 발생시키는 과정에서 wake vortex를 생성하며, 항공기 중량과 항공기 주위의 기상(특히 바람 vector)에 따라 wake vortex의 크기와 그 소산속도가 결정된다. 이러한 Raw data 정보는 항공기에 장착된 FMS와 Sensor를 통해 수집될 수 있으며, 이를 ADS-B를 이용하여 지상관제기관과 주변항공기에 전파하면, 실시간으로 매우 정확한 후류크기와 영향범위를 확인할 수 있고, 이로써 보다 안전하고 효율적인 항공기 후류분리가 가능할 것으로 볼 수 있다. 본 자료는, 이러한 맥락에서 ICAO(ASBU)의 후류분리기준 축소를 통한 활주로사용증진 동향과, RTCA DO-260B의 부록(V) "Potential wake vortex and Arrival management ADS-B Application" 요지를 소개한다.

Ongoing SWIM(System Wide Information Management) with the United States and European countries as the center is a part of the ASBU(Aviation System Block Upgrade) program improved performance of aeronautical data system in the International Civil Aviation Organization and a core technology of Integrated Aeronautical Data Management Network to elevate service through digitally aeronautical information management. Therefore, in this paper, we analyze SWIM architecture and network applied the concept of SOA(Service Oriented Architecture), and propose methods of implementation transforming applications operating established legacy aeronautical data system into integrated aeronautical data management network through adapter technology. This will allow development of middleware and application suitable for the next generation infrastructure network environment for efficient ATM(Air Traffic Management)and provide timely required information for users.

AeroMACS spectrum is a national resource internationally allocated by ITU at WRC-07. AeroMACS is an airport broadband mobile communication infrastructure based on WiMAX-based IEEE 802.16e that enables real-time video, graphics, voice, and high-speed data transmission. With the approval of ICAO's development technology standards in 2008, 50 airports in 11 countries have already completed the testing of D-TAXI or A-SMGCS technology using the AeroMACS infrastructure in 2019, starting in the United States in 2009. With many advantages in safety and convenience in terrestrial telecommunications operations, the system is becoming an area of performance improvement for airport operations in accordance with ICAO's ASBU plan. This paper examines the current status of domestic development of AeroMACS and lists service areas applicable to airlines and operators. It also seeks to promote safe and efficient next-generation airport mobile communication system services by presenting feasible partners management in the mobile area and use of aircraft communication systems for active technology development.

The automatic dependent surveillance - broadcast (ADS-B) system which is a core system of aviation system block upgrade is designed and implemented. The ADS-B system consists of the 4 blocks and 10 units, and filtering algorithm is applied to the implemented ADS-B system. To evaluate a performance of the implemented ADS-B system, real aircraft position data is used and compared reliable radar data. The comparison results show that average position difference of 99.57 m. In addition, comparisons of aircraft position data between the implemented ADS-B system employing filtering algorithm and the conventional ADS-B system under various situations are carried out, such as aircraft turning, taking off, landing, and cruising. The comparison results show that average position difference of 8.02 m.
