An ionospheric heater, or an ionospheric HF pump facility, is a powerful radio wave transmitter with an array of antennas which is used for research of plasma turbulence, the ionosphere and upper atmosphere. These transmitters operate in the high frequency (HF) range (3-30 MHz) at which radio … Meer weergeven • EISCAT-Heating operated by the European Incoherent Scatter Scientific Association (EISCAT) at Ramfjordmoen near Tromsø in Norway, capable of transmitting 1.2 MW or over 1 GW [1] [2] effective radiated power Meer weergeven • Arecibo Observatory also had a HF facility for ionospheric modification.
