초록

요즘 차량 네비게이션 시스템은 큰 관심 분야이다. GNSS(Global Navigation Satellite System)은 실외 측위를 위한 기술 중 핵심적인 기술이다. 그러나 GNSS는 높은 정확도와 신뢰도를 제공하지 못한다. 이러한 이유로, 우리는 차량의 GNSS 성능의 정확도를 향상시키기 위하여 Network-RTK를 적용하였다. 이 Network-RTK 모드에서 GNSS 에러는 급격히 감소하게 된다. 본 논문에서 우리는 ntrip client 프로그램을 설명하고 다양한 환경에서의 실험 결과를 보여준다.

These days land vehicle navigation system is a subject of great interest. The GNSS(Global Navigation Satellite System) is the most popular technology for out door positioning. However, The GNSS is incapable of providing high accuracy and reliable positioning. For that reason, we applied Network-RTK in vehicle to improve the accuracy of GNSS performance. In this network-RTK mode, the GNSS error are significantly decreased. In this paper, we explain ntrip client program for network-RTK mode and show the result of experiments in various environments.
