GRDS test-bed report

This document summarises the results acquired from testing the updated radio frequency interference (RFI) screening from the ground RFI detection system (GRDS) developed by Zenithal Blue Technologies (ZBT) and Research and Development in Aerospace (RDA). Data from the European Space Agency (ESA) Soil Moisture and Ocean Salinity (SMOS) mission is used to assess the RFI screening. At the European Centre for Medium-range Weather Forecasts (ECMWF) SMOS data is routinely monitored by comparing it to high-quality short-range numerical weather prediction (NWP) forecasts. Experiments using this monitoring system have been run to compare the current data quality with the quality of the GRDS screened data.
