Navigational display system
First Claim
Patent Images
1. A navigational display system, comprising:
- A. a TV monitor;
B. means for providing first and second coordinate navigation signals indicative of the position of said carrier relative to a navigational reference;
C. means for converting said first navigation signal into a calculated scaled quantity between zero and L, where L is the number of active TV lines to be displayed on the monitor'"'"'s TV picture;
D. means for converting said second navigation signal into a calculated scaled quantity across a TV line; and
E. means for displaying a mark in said TV picture at the appropriately calculated TV line and distance along that line.

Abstract
The position of a carrier from a navigational reference generates X,Y coordinate navigation signals which are scaled as distance along a TV line of a TV display and a line number in the frame of the TV picture. A continual updated track of a moving vehicle is therefore displayed on a TV monitor, and if a video disc is used, can be recalled from the non-volatile memory for later replay.

3. A display system for indicating the total navigational track of a carrier, comprising:
-
A. a TV monitor having an X-Y display made up of a plurality of scanned TV lines each line being divided into a pluarlity of adjacent equal time increments; B. storage means for storing signals to be displayed on said TV monitor; C. means for providing first and second coordinate navigation signals indicative of the position of said carrier relative to a navigational reference; D. means responsive to one of said signals for generating a line number signal K1, where ##EQU3## YN is said first navigation signal YS is the scale of said display in the Y direction L is the number of TV lines displayed Yr is the number of TV lines to a display reference point; E. means responsive to the other said navigation signal for generating an increment number signal K2, where ##EQU4## XN is said other navigation signal XS is the scale of said display in the X direction I is the number of adjacent equal time increments in a TV line Xr is the number of adjacent increments to said display reference point; F. circuit means responsive to said line number signal and said increment number signal for placing into said storage means a display signal, the displayed position of which from said display reference point is substantially proportional to the actual position of said carrier relative to said navigational reference. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
