23 Conclusion: vision of space-based observation in By 2040, the Roshydromet space constellation should include 3 Electro GEO satellites, 2 Arctica highly elliptical orbit satellites, 4 Meteor and 2 oceanic LEO satellites. 2. All new satellite instruments (scanners, radars, and spectrometers) will have better spectral and space resolution in comparison with existing models. 3. Lifetime of LEO «Meteor-MP» satellites will be no less 7 years, for Electro-M GMS and Arctica highly elliptical orbit satellites - no less 10 years. 4. The constellation of Electro-M GMS (with backup option via Luch communication satellites) and Arctica satellites will provide coverage from about 75S to about 90N. 5. Roshydromet ground-based network and test sites will be used for validation of new satellite data and products, including those designed for climate change monitoring.
