The largest Key Science Program of the RadioAstron space VLBI mission is asurvey of active galactic nuclei (AGN). The main goal of the survey is tomeasure and study the brightness of AGN cores in order to better understand thephysics of their emission while taking interstellar scattering intoconsideration. In this paper we present detection statistics for observationson ground-space baselines of a complete sample of radio-strong AGN at thewavelengths of 18, 6, and 1.3 cm. Two-thirds of them are indeed detected byRadioAstron and are found to contain extremely compact, tens to hundreds of$\mu$as structures within their cores.
