The disclosure describes how, by starting with the final equation (11) in U.S. Pat. No. 4,177,579 and by making certain assumptions and by rearranging, collecting and reducing the equation further, the apparatus to produce the same result will cut the cost dramatically. All of this is accomplished in accordance with a demonstrated mathematical relationship.

Over wide altitude ranges, signals representative of the altitude of an eyepoint viewing a synthetic grid pattern on a ground reference plane are scaled to provide strong signals. These strong signals are used to electronically define the intersection of a line of sight from the eyepoint to the grid pattern so that a clearly defined grid pattern as viewed over the wide altitude range can be displayed.
