Sentinel-1 is a space network of three* spaceborne C-band synthetic aperture radar (SAR) sensors developed and operated by the European Space Agency under the Copernicus Earth Observation programme. This website is the result of the joint effort of Aresys and ESA and it aims at providing viewers with information (maps and classification) about the radio-frequency interferences (RFI) cases as observed from the C-band measurements made by Sentinel-1. Additional information/analyses would be required to assess the actual impact from these RFI into Sentinel-1 measurements and to determine whether the RFI in this website represent “harmful interference”in the sense of article 1.169 of the Radio Regulations.
Starting from June 2019, two maps are produced for each S-1 orbit cycle (12days) of each sensor: an RFI probability map and an interactive RFI map showing the main events. Additionally the RFI database of each orbit cycle can be downloaded.
For further details about how the RFI maps are generated, please refer to the technical specification.
* Two satellites are currently in orbit; the third satellite is planned for launch in 2023.
