ABSTRACT:
A navigational plotter consisting of a triangular shaped navigational plotter, having two angle members and a rounded third corner employing a compass rose and a central orientation point for use as a navigation aid in combination with LORAN computerized navigational system or alternative Global Positioning Navigational Systems. This navigational plotter enables a navigator to easily locate the position of his ship on a chart by using input from the LORAN/GPS systems and by the use of this true course chart calculator which provides a course for checking the computerized course information and assists in avoiding obstacles in the path of travel not shown by the LORAN or GPS systems. When used with a LORAN or GPS system, the navigational plotter allows the navigator to plot a course on a chart or map and then to quickly locate the current position, orient the plotter correctly and get an overview of the true course.
