Abstract

A navigation apparatus (100) for assisting a user in the steering of a craft is described. The apparatus comprises: processing means (102) arranged to receive a magnetic compass signal from a magnetic compass (106) indicating the magnetic field direction at a current geographic location and to generate navigational data corresponding to the magnetic field direction. The apparatus also comprises display means (108) arranged to generate and display a rotatable image of a compass, to be responsive to the navigational data received from the processing means to orient the compass image with respect to a current heading marker on the display, and to display a graphical image showing a pre-programmed course to steer in relation to the compass image. The image is displayed such that any difference between the course to steer and the current heading can readily be determined graphically by the use of the apparatus.
