You use free software to calculate the quickest route by public transport, or your car's navigation system helps you avoid a traffic jam. None of this would be possible without the global navigation satellite systems (GNSS) technologies which use Earth-orbiting satellites, networks of ground control stations, and receivers to provide accurate positioning and navigation information. We rely on this in aviation, maritime, rail and road transit.
How do GNSS technologies make your globetrotting easier?
