Paper Abstract

A technique capable of improving the navigation system accuracy of operational systems using low-altitude correlation update information is desired. The technique makes use of the unique signature of the land mass passing beneath the vehicle to establish its position history and update its inertial navigation system. The generic types of sensors available to provide external mapping data for low-altitude correlation, the correlation performance measures developed for system analyses and the simulation studies performed to validate these performance measures are described. This paper will emphasize the ability to and the importance of developing analytical techniques in predicting the behavior of correlation update or image matching systems both in terms of fix accuracy and probability of correct correlation or acquisition. This type of analysis validated first by simulation and later by flight test results provides a solid basis on which to develop the system and bring it into operational utility with a high degree of confidence.
