Radar navigation system

Image Number 2 for United States Patent #4893127.

A low cost electronic navigation system including a Loran receiver and a marine radar unit adapted to receive vessel position information from the Loran. A computer within the radar unit uses successive Loran outputs to display vessel heading and the bearing of objects of interest such as other vessels or waypoints in graphic and numeric form. The navigator may accurately determine the bearing of such objects of interest in magnetic or true form. Other modes are of particular use when the navigator is interested in using the system to maintain a desired course, to avoid obstacles, or to determine if and by how much he must change his present course to return to the desired course.
