Аннотация:Planned space- based ultra- high- energy cosmic- ray detectors ( TUS, JEM- EUSO and S- EUSO) are best suited for searches of global anisotropies in the distribution of arrival directions of cosmic- ray particles because they will be able to observe the full sky with a single instrument. We calculate quantitatively the strength of anisotropies associated with two models of the origin of the highest- energy particles: the extragalactic model ( sources follow the distribution of galaxies in the Universe) and the superheavy dark matter model ( sources follow the distribution of dark matter in the Galactic halo). Based on the expected exposure of the experiments, we estimate the optimal strategy for efficient search of these effects.
