The micro-satellite COMPASS-2 launched on May 26, 2006. The satellite project has an exploratory
character and aims first of all to detect the ionosphere plasma anomalies linked to seismic, meteo and
human activity, precisely determining their characteristics, such as the EM frequency spectrum and
plasma density structures of disturbances in the ionosphere and the upper atmosphere, and the
corresponding precipitations of particles, systematically. It will provide the necessary data to work out
theories and models likely to explain their origin. The observations made by the COMPASS-2 has the
very great advantage of very rapidly covering almost the whole of the active seismic regions in the
world and monitoring the effects of a large number of earthquakes. COMPASS-2 has the capacity to
carry out precise and systematic measurements around the Earth and thus to collect a maximum
number of events (http://www.compass.izmiran.ru for more details about the mission). Without
modifying the payload, COMPASS-2 is capable for example of studying the influence of storms in
relation between Sun and Earth, and of assessing the impact of human activities on the ionosphere. The
detailed COMPASS-2 mission and payload description and also some first results of measurements will
be presented.
