EARTH OBSERVATION INSTRUMENTS
MeOp/SG (MWI)
(MicroWave Imager)
MetOp SG is a joint project of the European Space Agency and Eumetsat (EPS) that will make available in few years the most accurate weather forecasts ever performed.
OHB Italia S.p.A. is responsible for the MWI instrument that will be on board of three satellites. MWI is a conically-scanning microwave radiometer that provides measurements of precipitation, observations of clouds, snow, sea ice coverage, water vapor, temperature and surface images.

Features:
Power: 220 W |
Mass: 250 kg |
Sensor Head Dimensions: D 1.6 m, H 1.75 m |
Continuous rotation: ~ 200 million revolutions in space at 45 rpm |
Multi-beam architecture with 24 channels from 18.7 to 183.31 GHz |
Data rate: 1200 kbps |
CIMR
(Copernicus Imaging Microwave Radiometer)
It is an Earth Observation programme co-funded by the European Space Agency and EU member states in the frame of the ‘High Priority Copernicus Missions’. Agenzia Spaziale Italiana played a key role in financing the CIMR mission.
OHB Italia S.p.A. is responsible, as subcontractor for the development and production of the CIMR instrument in relation to the two satellites.
CIMR is a conical scan multi-frequency microwave radiometer featuring multi-beam architecture, the largest antenna of its kind, state-of-the-art advanced radio-frequency interference detection and blanking techniques. It will ensure global daily coverage with 6 hourly-revisit in Arctic areas, for high-spatial resolution observations of sea-surface temperature, sea-ice concentration, sea-surface salinity and a wide range of other sea-ice parameters, providing a fundamental contribution to climatology and environmental sustainability.
