Abstract:	This paper introduces the development and application of an advanced GPS performance monitor. It uses the hardware architecture of the previously developed GPS Anomalous Event Monitor, with expanded functionality added in the post processing network. The advanced GPS performance monitor is capable of continuous real-time monitoring of GPS for applications that have accuracy, integrity, continuity or availability requirements. The monitor operates autonomously and can be controlled and updated through the Internet. The system is not only capable of detecting anomalous events and recording data for these events, but also provides an automatic event analysis capability. The monitor acquires and processes data from multiple sources, such as sampled RF signal, GPS receiver output, notice advisories to NavStar users (NANU), and integrates analysis results into user-friendly reports. Regular GPS users can receive a direct answer on whether they are affected by the events, or how they are affected by the events. Interested users can conduct research with the data presented in the reports.
