GPS og Galileo i samme boksen - Glonass og det kinesiske systemet må vente litt - Curt Lewis

U.S., Europe to Work on Enhanced Satellite Navigation for Aircraft Planes would receive signals simultaneously from U.S. and European systems, resulting in safer skies Navigation satellites for Galileo, Europe's Global Positioning System, are launched from French Guiana in November. Eighteen of the Galileo's planned 30 satellites are in orbit.  By ANDY PASZTOR Aviation authorities are moving to improve the accuracy and reliability of satellite navigation by enabling aircraft in the future to simultaneously rely on separate orbiting systems run by the U.S. and Europe. Such proposed changes, recently endorsed by the U.S. Federal Aviation Administration's top outside technical advisers, set the stage for major shifts in how pilots will use space systems for precise position data and flight routes. The upshot would be safer skies because of more exact information about locations of planes and reduced likelihood of gaps or hacking of signals by making more satellites available to users.
