HF radio propagation prediction is the process of using computer models to predict the behavior of high-frequency (HF) radio waves as they travel through the Earth's ionosphere. High-frequency radio waves can be used for long-distance communication, but their propagation is heavily influenced by ionospheric electron density and geomagnetic disturbances caused by space weather conditions caused by solar activity.
HF radio propagation prediction models consider a number of factors, including maximum usable frequency (MUF) and receiver and transmitter locations. Predictions based on real-time MUF maps
can help radio operators and other HF radio users plan their communication activities more effectively.
