  19. High-elliptical Orbits Satellite System "Arctica " • Conclusions • To a great extent the progress of global and regional numerical weather forecasting, as well as providing safety navigation along Northern Sea Route together with many other Earth monitoring problems depends on the capabilities to provide hydrometeorological information for the Arctic region (at the latitudes higher than 60 deg. N) in quasi-continuous mode with high temporal resolution. • 2. Geostationary meteorological satellites cannot provide such information and therefore the proposed "Arctica" system should supplement existing global satellite observation system. • 3. Russia has great experience on design and exploitation HEO satellite systems, as well as the technical stock on the development of "Electro-L" and "Spectr-R" type spacecrafts. Based on this Roscosmos and Roshydromet (as responsible Russian governmental bodies) propose to realize "Arctica" project in the frame of wide international cooperation.
