Galileo signal reflections to monitor waves and weather at sea

November 29, 2007 For the first time a signal from a Galileo satellite - the European alternative to GPS - has been captured after reflection off the ocean surface. The successful experiment carried out by Surrey Satellite Technology Ltd (SSTL) and the University of Surrey demonstrates the potential for determining the weather at sea with remote sensing satellites. The development offers the possibility of deploying a constellation of small satellites to take measurements over the oceans where there are large gaps in forecast knowledge at present. Such a system could be used to provide severe weather warnings to mariners, data for global climate change models and even the potential to detect tsunamis.
