We present the Radio-wave Apparatus for Investigating Solar & Earth interference (RAISE), a compact low-frequency radio payload proposed for hosting on the SMiLE mission. Operating from Low Earth Orbit, RAISE targets a spectral regime that is largely inaccessible from the ground due to ionospheric effects. The payload is designed to enable space-based observations of low-frequency solar radio emissions while simultaneously characterizing terrestrial and ionospheric radio frequency interference in the near-Earth environment. RAISE employs mode-dependent Earth-pointing and Sun-pointing observations to generate dynamic spectral measurements relevant to space weather studies and low-frequency radio mission planning. As an experimental and technology demonstration payload, RAISE provides essential heritage for future space-based low-frequency radio astronomy and space weather missions.
