Finally, recently completed the first step in the project, managed by the European Union under the name Galelio where the European Union has started service part of this project bear the name of EGNOS and are and if they do not amount to an integrated navigation system as an independent entity – and it is expected to achieve the target of the project Galelio when it is completed fully – but it is currently designed to exploit the capabilities of satellite imagery of the project to increase the effectiveness of the system of traditional GPS and access to accurately determine the location through traditional navigation devices to the area of 6 feet compared to only 60 feet of ocean is the accuracy of the GPS system alone.
EGNOS service already entered into activation as the most modern navigation devices that were sold during the past period, within the EU have already hidden support for this service prior to release and that was to take advantage of the EGNOS service is still restricted to only 27 countries of the EU at the moment .
