Modeling of Failure of GPS Satellite for Realization of Anomalous Signals on Real-time

Abstract

GPS is utilized on various areas such as navigation, geodetic survey, cartography, time synchronization, etc. And a dependence of GPS is increased. Therefore, the integrity monitoring of anomalous GPS signal have been researched actively. Anomalous GPS signal can be occurred by failure of GPS satellites, rapid change of ionosphere due to solar storm, errors of navigation messages, and interference signals, etc. In this paper, a study for realization of anomalous signals on real-time was performed. Using RINEX data on occurred failure of GPS satellites clock and orbit, influences in receiver were analyzed. And anomalous signals to inject on live signals were modeled through results of analysis.y.
