EU launches free EGNOS satnav system

The European Commission has announced the official start of operations of the European Geostationary Navigation Overlay Service (EGNOS), a satellite based augmentation system (SBAS) that improves the accuracy of the current US Global Positioning System (GPS) and Russian GLONASS system signals from about ten meters to two meters. Like the U.S. GPS, the EGNOS Open Service is accessible free of charge to any user equipped with a GPS/SBAS compatible receiver within the EGNOS coverage area, which includes most European states and has the built-in capability to be extended to other regions, such as North Africa and EU neighboring countries. Most receivers sold today in Europe meet that requirement. Read More

Galileo signal reflections to monitor waves and weather at sea

By - November 28, 2007 1 Picture
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. Read More
