The SMOS mission makes global observations of soil moisture over Earth’s landmasses and salinity over the oceans. Variations in soil moisture and ocean salinity are a consequence of the continuous exchange of water between the oceans, the atmosphere and the land – Earth’s water cycle. Mier Comunicaciones produced the 72 high-sensitivity L-band receivers used to pick up faint radio signals from our planet’s land and sea surface, to build up a picture of global soil moisture and ocean salinity patterns. This achievement has in turn opened up commercial opportunities, such as contracts for the new generation of US mobile telecommunications satellites relying on nearby wavelengths, including Loral Space Systems’ ICO/DBSD and Terrestar satellites.
