UK-DMC GPS Reflectometry Experiment: Measurements and Validation


Earth-reflected Global Navigation Satellite System (GNSS) signals have become an attractive tool for remote sensing since airborne and spaceborne experiments have proven the viability of GNSS reflectometry concept. A Global Positioning System (GPS) reflectometry experiment was added to the UK Disaster Monitoring Constellation Satellite (UK-DMC, launched in October of 2003 ) as a secondary payload. The onboard GPS receiver, in addition to its normal operation, is being operated in a scatterometric approach to detect ocean's reflected signals and infer geophysical quantities (Sea surface-wind speed, wave height, ..). The talk will describe the experiment and highlight the scientific results: the successful measurements obtained to date with the validation of the data .
