Sura Ionospheric Heating Facility

The Sura facility is a research complex near Vasilsursk dedicated to studying the ionosphere through radio transmission. It contains three 250-kilowatt transmitters and 144 dipole antennas arranged across a 300-meter square ground area.

The facility was established in 1981 with Soviet funding to investigate how radio waves affect the ionosphere. This founding shaped its focus on high-frequency research methods that continue to guide experiments at the site today.

The site represents a space where scientists from multiple nations share knowledge about how radio waves affect the upper atmosphere. You can walk around the antenna field and observe how researchers from different countries collaborate on the same experiments.

The site welcomes visitors interested in radio science, though checking access conditions beforehand is wise. The sprawling antenna field is best explored on foot, particularly when weather permits comfortable walking around the installations.

The facility pursues similar radio wave experiments as the American HAARP project, with both sites examining how radio signals behave in the upper atmosphere. This parallel research effort makes it a fascinating comparison point for anyone interested in large-scale atmospheric science projects.
