GNSS integrity Performance analysis in Korean region

한국지역에서 GNSS 무결성 감시의 가용성 예측

  • Published : 2007.12.31

Abstract

this paper, integrity analysis in Korean region using GPS, modernized GPS, Galileo, SBAS and GBAS is given. The simulation results show that Cat. I requirement can be met using modernized GPS and Galileo alone, however, Cat. II and III are not met even augmenting SBAS because of VPL. A more efficient augmentation such as GBAS reduces VPL to meet Cat. II and III requirements in Korean region. This result will be used to design and implement not only an augmentation system but also regional satellite navigation system.

본 논문에서는 GPS, GPS 현대화, Galileo, SBAS 및 GBAS등의 항법 시스템을 모두 고려하여 한국 지역에서의 GNSS 무결성 감시의 가용성을 분석하였다. 현대화된 GPS, Galileo 및 SBAS를 사용하면 Cat. I에 근접한 성능을 얻을 수 있음을 시뮬레이션을 통해 확인 하였다. 그러나 여전히 수직오차의 영향으로 Cat. II 및 III를 만족시키지 못하므로 GBAS와 같은 보다 개선효과가 큰 보강 항법 시스템이 필요함을 확인하였다. 본 논문의 연구 결과는 보강시스템의 구축뿐 아니라 지역 위성항법시스템 구축을 위한 기초 자료로 활용될 수 있다.
