A roadmap towards a space-based radio telescope for ultra-low frequency radio astronomy [PDF]

Advances in Space Research, 2020
The past two decades saw a renewed interest in low frequency radio astronomy, with a particular focus on frequencies above 30 MHz. However, at frequencies below 30 MHz, Earth-based observations are limited due to a combination of severe ionospheric distortions, almost full reflection of radio waves below 10 MHz, solar eruptions and human-made radio ...

The radio environment for a space-based low-frequency radio astronomy instrument [PDF]

2019 IEEE Aerospace Conference, 2019
Opening the last frequency window for radio astronomy in the sub - 30 MHz region includes a few challenges. First of all, at frequencies below 30 MHz the Earths ionosphere severely distorts radio waves originating from celestial sources, and it completely blocks radio waves below 10 MHz.

Orbiting Low Frequency Array for radio astronomy [PDF]

2011 Aerospace Conference, 2011
Recently new and interesting science drivers have emerged for very low frequency radio astronomy from 0.3 MHz to 30 MHz. However Earth bound radio observations at these wavelengths are severely hampered by ionospheric distortions, man made interference, solar flares and even complete reflection below 10 MHz.
