We are pleased to welcome you at the VIRAC2012 Conference \Advances in Radio Astronomy of Near-Earth Environment" which is organized by the Engi- neering Research Institute \Ventspils International Radio Astronomy Centre" of the Ventspils University College. This conference is dedicated to methods and instrumentation of radio astro- nomical research of the near-Earth environment. We offer the opportunity to discuss the latest developments in the two important fields: the studies of the state of the ionosphere and studies of the population of near-Earth satellites and space debris. Humanity intensively explore and use the near-Earth space and if, a decade ago the launch of satellites was possible only for a few world leader countries, nowadays every small country and even institute is able to create its own satellite. In the near future these capabilities will be available even to small business. So, now question of controlling the near-Earth space for
