3 MHz space antenna

J I Katz, J Krassner

Abstract

Little is known about the radio astronomical universe at frequencies below 10 MHz because such radiation does not penetrate the ionosphere. A Cubesat-based antenna for the 1–10 MHz band could be rapidly and economically deployed in low Earth orbit. When shielded by the Earth from Solar emission, it could observe weak extra-Solar System and outer Solar System sources. We suggest possibly observable sources, and application to study of the topside ionosphere.
