Abstract:

A proposed system is described for obtaining aircraft navigation checkpoint information by performing on-board comparisons of sensed horizon profiles and stored reference horizon profiles. Two variations of the system are presented and analyzed for penetration missions where the aircraft pilot maintains low-altitude flight between ridges to obtain terrain masking. System parameters and computation implementations have been investigated by using terrain data obtained from topographic maps and performing simulation analyses. Results of these analyses are shown and used to investigate system feasibility and select the best parameter and computation implementation.
