The present invention relates to a method for calculating an optimal protection level for local area differential-global navigation satellite systems (GNSS) for unmanned aerial vehicles and a system thereof and, more specifically, to a method for decreasing a protection level of the system by optimizing and allocating integrity and continuity probabilities of each failure mode in real time based on integrity parameters of ground stations in an unmanned aerial vehicle mounted system and a system thereof. According to the present invention, integrity information is broadcasted in a ground station system to calculate a protection level of each system failure mode and the optimal protection level removing maintainability is calculated from an unmanned aerial vehicle mounted device.

    본 발명은 무인항공기용 지역 보강시스템을 위한 최적 보호수준 산출 방법 및 시스템에 관한 것으로, 보다 상세하게는 무인항공기 탑재시스템에서 지상국의 무결성 파라미터를 기반으로 각 고장 모드의 무결성 및 연속성 확률을 실시간으로 최적화 할당함으로 시스템의 보호수준을 감소시키는 방법 및 시스템에 관한 것이다. 본 발명에 의하면, 지상국 시스템에서 각 시스템 고장 모드의 보호수준을 산출하기 위한 무결성 정보를 방송하고, 이를 토대로 무인항공기 탑재 장치에서 보수성을 제거한 최적의 보호수준을 산출한다.
