High Frequency Radio Communications
Recently, scientists at the Indian Institute of Geomagnetism (IIG) developed a model for radio wave propagation through the ionosphere, which can assess the impact of space weather and aid in the planning and operation of High Frequency (HF) radio communications.
Key Points
- Location and Role of Ionosphere: The ionosphere is located in the upper atmosphere between 50 to 400 miles above the Earth's surface. It acts as a gateway for radio communication between the ground and space.
- HF Radio Communication: Certain frequencies of radio waves, particularly in the HF band, are reflected back to the ground by the ionosphere, enabling ....
