Abstract

This research models the performance of the proposed augmentation system as well as three and four-ball TDOA satellite systems and AOA and three-ball TDOA airborne systems individually, and performs geolocation estimate fusion via a variety of techniques to determine the increase in performance due to geolocation estimate fusion in operationally representative scenarios. It also introduces a high fidelity surface of the earth constraint based upon a digital elevation model across all geolocation algorithms. The results from this research show that the proposed augmentation system does have military utility when combined with other geolocation systems of similar or worse individual performance. Additionally, it demonstrates the performance improvement due to correct application of a surface of the earth constraint, and the most appropriate estimate fusion technique.
