This paper develops an UAV navigation and guidance system for air-to-ground target tracking in an urban environment. The integrated vision/inertial navigation filter is designed to simultaneously estimate the target and UAV states without GPS. The guidance law which achieves tracking while enhancing the navigation accuracy is proposed.
