METEOR-Ì ¹1 Spacecraft (Future Spacecraft)

Mission Objective
Global observation of atmosphere and Earth’s underlying surface to acquire hydrometeorological and heligeophysical data on a regular and global basis.

Tasks to be Fulfilled

• Acquiring multi-band images including radar ones and measurements of the „Earth’s surface – atmosphere“ system outgoing radiation over different ranges of electromagnetic spectrum;


• Obtaining heliogeophysical data;


• Acquisition and transmission of data from DCPs of different types (ground, ice, drifting)
