Institute of Ionosphere of National Academy of Science of Ukraine and Ministry of Education and Science of Ukraine

Director - Igor F. Domnin

Main Scientific direction is: Earth ionosphere physical properties under natural and artificially disturbed conditions.
Sircumterrestrial space and space weather phenomena investigations are carry out by Ionospheric Sounder - high informative radiophysical ground-based facility. It include designed in Institute unique incoherent scatter radars equipped most in the world two-mirror zenith parabolic antenna 100 m diameter and fully steerable parabolic antenna 25 m diameter. The scientific equipment also includes high frequency heating facility of effective power 300 MW equipped by wide-band array antenna 300 m 300 m. The purpose of the last is artificial ionospheric disturbances investigations. There is an ionosonde at the same place. Cabinet if Ministers of Ukraine at 1991 classified the Ionospheric sounder as National property of Ukraine.

By incoherent scattering method ionospheric data covered more then three solar activity cycles are obtained. Effects of natural geospace disturbances caused by solar flares and solar eclipses as well as effects artificial ionospheric disturbances caused by spacecrafts launches and powerful HF radio wave radiation are investigated.
