Then by overlaying specific HSIP data, the 18 CIKR sectors being affected can be visualized.By decomposing and drilling down to the PNTIP data theme layer, similar to the HSIP data set, you will be able to see interference report plots.

19. UNCLASSIFIED National Sensor Capability Coordinate domestic capabilities to identify, analyze, locate, attribute, & mitigate sources of interference to the GPS & its augmentations. System-of-Systems approach to provide real-time monitoring (preparedness), location & notification (response) of GPS interference for protecting the Nation’s CIKR sectors. Designed with government & commercial hardware Persistent monitoring yields situational awareness Timely response to anomalies Sensor placement based on PNT CIKR Criticality Remains operational when GPS systems is “stressed” Collective Effort by various USG entities Significant Cost & Risk reduction by taking full advantage of mature, existing systems “Patriot Watch” is a notional national sensor capability…. We are evaluating the possibility of tying together… an array of some sort to protect US domestic interests as part of the national interference detection system. Future sensor capabilities will be specifically placed to further protect CIKR. “Patriot Watch” is a notional national sensor capability….

20. UNCLASSIFIED Path to a National Sensor Capability Patriot Watch will mature over the next several years. We are testing an initial sensor capability towards the end of this year and again next year around the same timeframe. We hope to have a comprehensive understanding of all technical capabilities which could provide the best protection of the GNSS spectrum sometime in 2010. As more and more of our infrastructure becomes dependent upon space-based PNT signals, we will have to become more vigilant in monitoring for interference.
