Satnav Overview

• Satnav (satellite navigation) will replace nearly every other form of radionavigation, meeting or exceeding the accuracy, reliability, and global coverage of land-based systems.
• It is supported by world aviation agencies to eliminate the high cost of servicing thousands of VOR, ILS, NDB, and other ground stations.
• Benefits will multiply as GPS (U.S. system) is joined by Europe's Galileo.
• Land-based stations will continue to operate well into the 21st century to avoid obsoleting the huge avionics investment in old aircraft.
