The measurements of the radar altimeter play a significant role in an ESA programme referred to as CAMMEO (for Co-ordinated Approach to Markets for Marine Earth Observation). The programme involves research centres and value-added companies working together with the Norwegian Meteorological Service to provide near real-time satellite information on sea-state alongside regular forecasts. Users of the service include shipping, search and rescue operations and other specialist marine operations.

The principal sensors providing data are the radar altimeters carried by JASON, Envisat and ERS-2, and the wind scatterometer on QuikSCAT.

The type of information that can now be made available to ships and other marine users with regular updates throughout the day following a satellite overpass, will be demonstrated.
