Sudden Ionospheric Disturbance Grid.
Abstract
The technique described will allow controllers to quickly determine (1) whether a short wave fade in progress will affect any of their hf circuits, (2) the degree to which each circuit is affected, (3) alternative frequencies, and (4) alternative traffic routes available. The only required input parameter is 1 - 8A X-ray flux. The computer program continuously displays the LOF over any number of preselected hf transmission paths in predictive, real-time, or historical mode. The technique was designed primarily for naval commands which control hf systems covering large geographical areas, such as Communication Area Management Sections at Navy Communications Stations and HF Direction Finding Net Control.
