<p>A navigation and guidance system (200) which directs a user toward a desired destination. Position and steering information are integrated into a single display (200) to allow the user to immediately determine whether the correct course is being traveled, and to inform the user of any directional changes which may be necessary to be directed toward the desired destination waypoint (220). The user's position and course are determined by a navigation system and indicated on the display as a directional pointing icon, such as a line or arrow. The destination is displayed as a point. The user's Point of Closest Approach (PCA) (210) can then be calculated according to current position (218), course (216), and the position of the desired destination (220). As the user's course gets closer to the bearing (212) of the destination waypoint, the PCA indicator can correspondingly shift with the user's movements. By superimposing the PCA (210) over the destination waypoint, the user may precisely steer his or her craft to the desired destination.</p> |
