A navigational plotter in which a geographical map or chart has marked thereon lines of position corresponding to the Omega or Loran navigation system aids, for example. The intersections of the lines of position with a base line on the chart are recorded in coded form on a separate strip of the chart. The coded signals on the chart strip are read out by the plotter, so that the position of the marker or indicator of the plotter may be read out directly in terms of lines of position corresponding to Omega or Loran systems. The marker or indicator of the plotter may also be positioned directly from information obtained in terms of Omega or Loran lines of position.
