The Electromagnetic Systems group has completed an extensive antenna test campaign for a potential future satellite mission in cooperation with AIRBUS and ESA.

The Electromagnetic Systems group has completed an extensive antenna test campaign for a potential future satellite mission in cooperation with AIRBUS and ESA. The SMOS-IRMI mission will be a follow-up to the still operating SMOS mission for which the on-ground calibration of the antenna flight hardware also took place at the DTU-ESA Facility in 2006-2007. The objective of the SMOS mission(s) is to measure the Earth’s soil moisture (SM) and ocean salinity (OS) for monitoring the climate and forecasting climate changes; this is done with a radiometer system that receives the natural electromagnetic radiation from the Earth. For SMOS-IRMI, the antenna system consists of 87 individual and dual-ported elements whose radiation performance must be calibrated to a very high accuracy in order that the soil moisture and ocean salinity can be determined. In this phase A study, 7 central dual-port elements of the antenna system were calibrated. For more information, please contact Olav Breinbjerg.
