EARTH OBSERVATION INSTRUMENTS

MWI

(MicroWave Imager)

It is a conical scan multi-frequency microwave radiometer providing measurement of precipitation, observations of clouds, snow, sea-ice coverage, water vapor, temperature and surface imagery.

MetOp mission, a program that was jointly established by ESA and the European Organisation for the Exploitation of Meteorological Satellites (Eumetsat), froms the space segment of Eumetsat’s Polar System (EPS).

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

CIMR

(Copernicus Imaging Microwave Radiometer)

It is an Earth Observation programme co-funded by ESA and EU member states in the frame of the ‘High Priority Copernicus Missions’. ASI – Italian Space Agency – played a key role in financing the CIMR mission.

OHB Italia is responsible, as subcontractor of Thales Alenia Space Italy, for the development and production of the CIMR instrument for two satellites with an option for a third satellite.

The CIMR instrument is a conical scan multi-frequency microwave radiometer featuring multi-beam architecture, the largest rotating 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.
