C/NOFS / Pegasus XL
The Communications/Navigation Outage Forecasting System (C/NOFS) is owned and operated by the U.S. Air Force. C/NOFS is a prototype operational system designed to monitor and forecast ionospheric scintillation in real-time and on a global scale. Timely location of scintillation outage regions would enable the warfighter to modify mission plans and prevent potential mission failures by optimizing and tailoring communications routes, paths, and/or priorities and effectively use satellite communications, navigation, and surveillance assets. It will include three critical elements. The first is a space-borne sensor system consisting of seven proven sensors to provide data for global, real-time specification, and 4 hour forecast capability. The second is a series of regional ground networks that augment the space based sensors for real time, high resolution coverage in theater. The third is a forecasting/decision aid software package that produces tailored space environmental forecasts and warnings in the form of outage maps for the warfighter.
