Automatic navigation makes ocean-going and flying safer and less expensive: Safer because machines are tireless and always vigilant; inexpensive because it does not use human navigators who are, unavoidably, highly trained and thus expensive people. Unmanned deep space travel would be impossible without automatic navigation. Navigation can be automated with the radio systems Loran, Omega, and the Global Positioning System (GPS) of earth satellites. In some circumstances, such as when a submarine is deeply submerged or in a war zone where radio signals may be jammed, these aids are not available. Then we must use a self-contained system called inertial navigation.
