Series of 6 operational meteorological satellites in polar orbit.
Follow-on of the Meteor-2 series. Main improvemens: more performing platform and more instruments. The last two satellites hosting foreign instruments for ozone and Earth radiation budget, respectively.
National Russian programme: RosHydroMet responsible of the overall programme and of running the operational phase, Roscosmos responsible of the development of the space segment.
Satellites actively stabilised over 3 axes.
The design lifetime was 2 years.
Drifting orbits with high inclination.
Replacement policy based on frequent launches: average 1 launch / 1.5 years.
See detailed description at
Note: in the satellite descriptive sheets, because of uncertain EOL dates, a mission duration of 2 years has been assumed.
Data stored onboard and downlinked to RosHydroMet acquisition stations. Processed and disseminated by RosHydroMet.
