The European Commission launched a new technology, known as the European Geostationary Navigation Overlay Service (EGNOS), at a press conference in Brussels. It is now available free, to business and individuals. It improves the accuracy of current GPS signals across Europe from about ten metres to two metres
Thought this might have escaped the attention of some.
I know my Satnav(Zumo 550) requires a small change in the tools/system to make use of this new service. Others may or not.
