Welcome to the MERRByS website

The ocean is continually reflecting signals from radio-navigation satellites orbiting tens of thousands of kilometres above the surface of the Earth. These reflections carry the imprint of the sea-state; by capturing them from low Earth orbit with a GNSS receiver we can remotely sense the wind and waves.

The first satellite to demonstrate a wind and wave measurement service is the UK’s TechDemoSat-1.

On this site we present the results and allow access to the data.

This service has been implemented by Surrey Satellite Technology with partners National Oceanographic Centre with funding from the European Space Agency.
