Fusion of Reference-Aided GPS, Imagery, and Inertial Information for Airborne Geolocation

摘要

A remote sensor suite is described that utilizes kinematicrnand differential GPS, a digital camera, and a tacticalgradernInertial Navigation System (INS). The camera andrnINS are fixed to a scan platform housed in a turret. Thernturret is attached to the chin of a light, single-enginernaircraft. Real-time differential GPS positioning alongrnwith the real-time INS observations provide a pointingrnvector to a specific location on the ground, allowing therncamera to continuously stare at that location as the aircraftrnflies by. Post-mission integration of the camera positionrnand attitude, along with image information, can providernthe ground locations of any point in the image in WorldrnGeodetic System (WGS-84) coordinates.
