Tel Aviv-based start up Effective Space Solutions claims that its DeOrbiter microsatellites could not only be used to dispose of defunct geosynchronous satellites, but could also rescue a pair of errant Galileo satellites currently trapped in the wrong orbit and put them back into service.  Read More

The ESA's post launch team are ready to guide and take control of a twin set of Galileo satellites, undertaking a number of procedures and adjustments in order to ready the pair for orbital duties. The satellites are due to be hefted into orbit together atop a Russian made Soyuz rocket on August 21 from the ESA's launch site situated in French Guiana.  Read More

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

December 6, 2007 A new positioning system which will use Galileo, the future European global positioning satellite system, may prove to be a life saver for avalanche victims. Avalanches kill hundreds of people worldwide every year. In the United States annual avalanche deaths have averaged 25 for the last ten years, with 20 deaths occurring in the 2006-2007 season.  Read More

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
