"Experiments at the Space Vehicles Directorate's Gakona research facility in Alaska produced breakthroughs in the artificial generation of optical
emissions in the ionosphere by high-power radio waves. The facility, operated by the High Frequency Active Auroral Research program (HAARP), is
currently under construction to complete a planned 3.6 MW high frequency (HF) transmission capability. Nevertheless, it has already proven that it is
a unique research instrument to exploit emerging ionosphere/high-power radio technology for next-generation space-system concepts and operations.
A key feature of the HAARP array is the ability to transmit at the second harmonic of the electron gyro-frequency near 2.8 MHz. This gyro-harmonic
resonance provides a critical test of theories related to the space plasma processes that can be triggered via interactions with high-power radio
