  • Radio navigation aids are very important elements to provide information necessary for safe navigation using radio waves. Recently, the number of radio equipment using radio waves is increasing, and the air frequency interference by adjacent channels is very high. In addition, the use of irregular jamming that threatening radio navigation aids and satellite navigation system frequency is rapidly increasing. Therefore, it is urgent to ensure the safety of air waves. In this paper, we investigated the characteristics and frequency of the domestic navigation system. And we were analyzed the geographical separation standard for implementation of analysis program. Also, we implemented a program for the geographical separation distance analysis that applying international standards and recommended practices.

  • 3차원의 공간을 비행하는 항공기의 항행은 조종사가 직접 지상의 지형지물을 참조하며 비행하는 시각비행과 지상의 항행안전시설로부터 무선신호를 받아 비행하는 계기비행으로 구분되어 발전되었다. 현재 계기비행을 수행하기 위한 계기비행절차 수립에 기반이 되는 항행안전무선시설은 기존의 VOR(VHF Omni-directional Range), ILS(Instrument Landing System) 등의 지상기반 항행안전무선시설에서 GNSS (Global Navigation Satellite System)를 이용한 위성기반 항행으로 전환을 목표로 하고 있으며 항행체제 또한 기존의 Fix to Fix 항행체제에서 RNAV(Area Navigation) 체제로 전환되고 있는 추세이다. 계기비행절차는 항공기가 활주로를 이륙하여 항로로 진입하기 위한 계기출발절차(SID), 항로절차(Enroute), 항로에서 목적 공항의 지정된 활주로에 설정된 접근절차(Approach)로 인도하는 도착절차(STAR), 지정된 활주로에 착륙하기 위한 접근절차로 구분될 수 있으며 본문에서는 GNSS를 기반으로 하는 RNAV 절차(RNAVGNSS)에 대한 개괄적인 소개, 설계요건 및 RNAVGNSS 계기비행절차를 성공적으로 이행하기 위한 절차이행모델, RNAVGNSS 절차 수립에 중요하게 고려해야할 사항 등에 대하여 소개하도록 한다.

  • The Air Radio Station plays a role in creating skyways for aircraft and helping them fly safely through aviation mobile communication facilities (U/VHF transceivers) and various navigation safety facilities. It is necessary to remove large trees and weeds around the aircraft because accurate and safe signals must be provided without interruption. During the mowing work for the efficient management of landscaping facilities, there have been cases in which noise is introduced by Lawn Mower, which hinders control work. Accordingly, in order to analyze how mower affects air mobile communication facilities, the interference effect on air mobile communication facilities was analyzed for four types of mower, two-stroke, and battery type. As a result of the analysis, it was found that the two-stroke mower greatly affects air mobile communication facilities.

  • When a straight-in landing from an instrument approach using ILS or VOR/DME is not possible or desirable because of topographical reason or bad weather, a circling approach maneuver is initiated by the pilot to align the aircraft with a runway for landing. Visual contact with the runway is necessary while conducting a circle to land maneuver. This research is to develop a new warning system based on a convention marker system which alerts pilots to watch out for exceeding the circling approach area. The airborne system also uses the same receiver unit without any new installations. The objective of this research is to design and develop a Yagi antenna in a special form. The research includes computer simulations to determine the size of antenna radiation pattern and to compute an expected flight path in case of alarm to validate effectiveness of the system.

  • Obstacle defines all fixed and mobile objects, or parts thereof, that are located on an area intended for the surface movement of aircraft or extend above a defined surface intended to protect aircraft in flight or stand outside those defined surfaces and that have been assessed as being a hazard to air navigation. Aircraft operations are based on electronic supporting systems using radio frequencies to assist pilots. These frequencies can receive outside interference that change their courses or power, such as distortion, attenuation or reinforcements by an obstacle. This is a preliminary case study that shows the relation of instrument flight procedures and the degree of interferences introduced by a planned obstacle, which is a main bridge post, within the service volume of the radio navigation aids. For the purpose of this study, the case airport's data and it's VOR/DME and ILS systems' limitations are analyzed, as well as the relation of interferences between the obstacle and navigation aides were reviewed with the internal regulations in Korea.

  • In this paper, the method of interference analysis and its simulation have been suggested for the frequency sharing between aeronautical radio navigation systems and Link-16 platforms. In order to get the criteria for interoperability, the algorithm of interference analysis and protection ratio are derived to assure frequency sharing. Also the receiving power of wireless system has been illustrated with the help of radio propagation model of ITU-R Rec. P.1546 in VHF-UHF band. Finally the required receiving power or separation distance between DME/TACAN beacons and Link-16 ground station terminals has been considered based on system link budget in terms of evaluating interoperability as well as actual applications. As a result, if the suggested interference analysis and test set-up are applied to the field trial, it will lead to easy means to make a decision on interoperability over the existing incumbent systems.
