National Oceanography Centre using reflected GPS signals to enhance sea-state measurement and forecasting
Scientists at the National Oceanography Centre (NOC) are participating in the Technology Strategy Board 'WaveSentry' project to harness reflected signals from Global Navigation Satellites. Systems such as GPS will provide a new source of sea-state data for an improved information and forecasting service. The 'WaveSentry service will improve risk management for a wide range of marine operations in adverse conditions.
The NOC are working with partners in the private sector to develop and validate the methods needed (geophysical inversion) to retrieve geophysical information about sea state from measurements of satellite navigation signals reflected from the earth's surface, (GNSS-Reflectometry). GNSS-R was pioneered in 2005 by Surrey Satellite Technology Ltd (SSTL) on its UK-Disaster Monitoring Satellite, and promises to dramatically increase the temporal and spatial resolution of ocean wave data available from satellites.
Within WaveSentry, the new sea-state observations derived from satellite GNSS-R data will be ingested into a new information and forecasting tool developed by HR Wallingford to provide improved wave information services to maritime operators. The WaveSentry project paves the way towards the operational exploitation of GNSS-R sea state data from the UK TechDemoSat-1 satellite due to be launched by SSTL in late 2012.
Using techniques developed by NOC, WaveSentry has the potential to offer an enhanced world-wide sea-state measurement and forecasting service.
