"Meteor-M" ¹1 satellite

 

Description

"Meteor-M" polar-orbiting satellites are designed to be used to support Russian hydrometeorological and environment monitoring service and other organizations with operative satellite data, for the solution of following tasks:
  • weather analysis and forecasting on regional and global scale
  • sea water conditions analysis and forecasting (including ice cover monitoring)
  • atmosphere conditions analysis and forecasting for aviation purposes
  • analysis and forecasting of helio-geophysical conditions in near-Earth space environment, ionosphere and geomagnetic field conditions
  • global climate monitoring
  • emergency situations monitoring
  • ecological monitoring of the environment e.t.c.

The satellite is also capable of acquiring information from ground data collection platforms using international frequency band (401,9 - 402,0 MHz) at 400 bit/s rate.
