한국전자통신연구원에서는 2010년 하반기부터 방위사업청과 국방과학연구소에서 주관하는 국방위성항법 특화연구센터 사업에 참가하여 군 탐색구조 시스템 기술연구 과제를 수행 중에 있다. 1차년도에 기존 군 탐색구조 개념과 민간 탐색구조 시스템에 대하여분석한 결과를 토대로 M&S(Modeling and Simulation)를 수행하여, 군 탐색구조 시스템 구성시 탐색구조의 정확성, 신뢰성, 가용성을 향상시킬 수 있는 방안을 분석할 수 있는 툴을 목표로 개발하였다. 이를 위하여 군 탐색구조 시스템을 크게 사용자, 통신링크, 지상국, 운용환경 분야로 나누어 모델링 하였으며, 실제와 유사한 성능분석을 위하여 GIS 고도정보를 이용하여 사용자와 지상국 안테나 간의 Path Profile을 분석한 후 신호감쇄량을 결정한다. 여기서 사용자의 단말기 송출신호를 송수신하는 링크는 크게 지상망과 위성망으로 나누어 모델링하여 시뮬레이션하고, 근래에 북한의 재밍 사태에 따라 이슈가 되고 있는 재밍 항목을 추가하였다. 본 논문에서는 군 탐색구조 시스템 M&S 소프트웨어를 소개하고, 소프트웨어 설계와 기능 및 성능분석 결과를 나타낸다.
