Integrity Monitoring Technology on Reference Stations for Network RTK

M.Y. Shin, D.J. Cho, S.H. Park

Abstract:	Network RTK (Real Time Kinematic) is a precise positioning technique using CPC (Carrier Phase Correction) from reference stations within the network, and is constantly being researched for improved accuracy. However, researches for network RTK integrity monitoring have not been sufficiently studied, because network RTK has been mainly used on surveying for static or kinematic positioning. Recently, network RTK has been considered for dynamic navigation users requiring precise positioning performance, as well as surveying. Thus, researches for network RTK integrity monitoring are necessary. This paper presents an integrity monitoring technology that is adequate to network RTK. Anomaly detection algorithms are proposed to detect an abnormal signal caused by a faulty satellite, or by an irregular ionospheric or tropospheric characteristic between reference stations. The proposed anomaly detection algorithms are verified on an anomaly-free case, and represented real anomalous cases.
