Yacht sailing by satellite
A sophisticated detector, which will allow yachtsmen to pinpoint their location precisely, is to go on sale this month. The Magellan NAV 1«M, which will cost about SWM, is the size of a large pocket calculator and uses satellite radio transmissions to obtain extremely accurate navigational fixes.
A tiny, powerful computer “reads” signals emitted by satellites. These signals give an individual satellite’s precise position, as well as the time according to its on-board atomic clock. By comparing signals from three different satellites, a precise locational fix is then obtained and this is displayed on NAV lOW’s screen. Copyright London Observer.
