The Sura Ionospheric Heating Facility, located near the small town of Vasilsursk about 100 km eastward from Nizhniy Novgorod in Russia, is a laboratory for ionosphere research. Sura is capable of radiating about 190 MW, effective radiated power (ERP) on short waves. This facility is operated by the radiophysical research institute NIRFI in Nizhny Novgorod. The Sura facility was commissioned in 1981. Using this facility, Russian researchers achieved extremely interesting results regarding the ionosphere behavior and discovered the effect of generation of low-frequency emission at the modulation of ionosphere current. At the beginning, Soviet Defense Department mostly footed the bill. The American HAARP ionospheric heater is similar to the Sura facility. The HAARP project began in 1993.
The frequency range of the heating facility is from 4.5 to 9.3 MHz. The facility consists of three 250 kW broadcasting transmitters and a 144 crossed dipole antenna-array with dimensions of 300 m x 300 m. At the middle of the operating frequency range (4.5 � 9.3 MHz) a maximum zenith gain of about 260 (~24 dB) is reached, the ERP of the facility is 190 MW (~83 dbW).

Russian US cooperation
In March and May 2006 two
sessions of measurements in the framework of the SURA–HAARP experiment were carried out.
