  • Method and apparatus for real-time ionospheric mapping and dynamic forecasting
    Patent number: 5943629
    Abstract: A system and method are disclosed for providing a real-time map of ionospheric properties. An ionospheric model is provided that provides a baseline description of ionospheric properties. A primary data source is provided that is indicative of real time propagation data obtained for the ionosphere in the vicinity of a control point. The real time propagation data is indicative of the critical frequency for the ionospheric layer. The ionospheric model is modified based on the real time propagation data obtained for the ionosphere in the vicinity of the control point. This includes modifying the critical frequency for the ionospheric layer. In this manner, the ionospheric model is updated according to real time propagation data.
