Abstract

Flight recoder is used to analyze the accident factors and prevent the accident. In the analysis of the flight recorder, the most important factor is how to estimate the precise location of the flight. Traditional aviation navigation is based on stable sensors such as DME and VOR. In order to enhance the precision of the location estimation, the integrated navigation algorithm is designed to incorporate DME, Air data sensors and INS(Inertial Navigation System). The results demonstrate that the proposed algorithm can achieve better accuracy, comparing with the traditional navigation schemes, in flight location estimation.

비행기록장치는 사고원인 분석이나 사고방지를 위한 용도로 사용되고 있는데 비행 기록장치의 해석에서 가장 중요한 변수는 항공기의 위치 추정방법으로, 일반적인 항법과는 달리 항공항법에서는 정밀한 위치 추정이 쉬운 일은 아니다. 이에 본 논문에서는 정확한 항공기의 위치 추정을 위해 센서들의 특성과 비행기록장치 제한사항을 분석하였고 이를 바탕으로 비행기록장치 기반의 최상의 추정조건을 추출하여 복합항법알고리즘을 구성하고 시뮬레이션을 수행하여 기준 위치에 근사화된 위치를 추정해 낼 수 있음을 증명하였다.
