Electronic digital position and navigational plotter
First Claim
1. An electronic digital plotter for locating positions comprising:
- controller means for processing selected navigational data and chart data;
board means, electronically linked to said controller means, allowing for the overlay of navigational chart means, said board means generating a variable X/Y coordinate matrix and detecting the position of stylus means within the X/Y coordinate matrix;
display means, electronically linked to said controller means, for indicating the position of said stylus means relative to a predetermined position on said navigational chart means;
input means, electronically linked to said controller means, for inputting said selected navigational data and said chart data to said controller means.

Abstract
An electronic digital plotter for navigators which relieves the rigors of mechanical manual plotting of position on a chart. The plotter utilizes either a flexible or rigid board employing electromagnetic or capacitive resistance technology. It makes use of a fixed X/Y coordinate system to generate latitude and longitude coordinates from a chart overlay. The plotter employs a pencil or pen type stylus with interchangeable cartridge to locate position, derived from electronic position information on the board and hence on the chart. By comparing the location of the stylus to the input data, the plotter directs the user to the input location utilizing a visual, bullseye director display. Given ship'"'"'s position, on a dead reckoning track or expected destination or waypoint, the plotter gives course, speed distance, and transit time. The plotter can also accept inputs from hand bearing compass or ship'"'"'s heading compass. The plotter can be used to insert preselected positions into an electronic navigator or a preselected course into an autopilot.
