AB: Based on observational evidence, we suggest that a series of observational and modeling experiments could be carried out to demonstrate the viability of a satellite based earthquake prediction program based on a search for earthquake precursors. The satellite project has an exploratory character and aims first of all to detect the ionosphere plasma and the electromagnetic anomalies related to seismic, meteo and human activity. The observations made by the satellite have 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. The micro - satellite COMPASS - 2 launched on May 26, 2006. It has the capacity to carry out precise and systematic measurements around the Earth and thus to collect a maximum number of events. Without modifying the payload, like COMPASS - 2, is capable for 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 results of measurements are presented. We present electrodynamic model of the atmosphere - ionosphere coupling for interpretation of satellite data. Our model gives an explanation to some electromagnetic and plasma phenomena preceding typhoons and earthquakes by amplification of DC electric field in the ionosphere over disturbed region. This field is connected with the conductivity current flowing in the atmosphere - ionosphere electric circuit, which is formed by external electric currents generated in the lower atmosphere disturbed by typhoon and earthquake preparation processes. Appearance of such currents is associated with upward transport of charged water drops and aerosols in hurricane convection zone and enhancement of charge aerosols emanation with soil gases into the atmosphere caused by growing seismic activity. The most important property of this mechanism is that numerous electromagnetic and plasma effects can be explained by the operation of only one source - an amplification of DC electric field in the ionosphere. This source is controlled by the dynamics of atmospheric processes through modification of electrical parameters of the lower atmosphere and seismic processes. The presented model could be applied to studies of the plasma and electromagnetic effects of large - scale natural and technological disasters.
