An airborne gimballed imaging system comprises an agile, accurate, efficient, and versatile gimbal machine. It drives a long range imaging sensor payload over wide roll, pitch, and yaw angular ranges. Together with an embedded instrument computer, the gimbal machine is precisely servo-actuated at a sub-pixel resolution and navigated by a GNSS-Aided Inertial Navigation System (INS) with a 1m geospatial accuracy for imaging payload stabilization and pointing and high resolution fast frame image collection. A fast, high resolution and wide area mapping is one of the applications of the gimballed imaging system. It has been tested aboard Cessna 172 plane. It demonstrates: 1) a gimballed dual resolution fused imaging by adapting a pair of 47MP and 86MP mid-format cameras; 2) a fast wide swath mapping by using the gimballed imaging system, capable of collecting a 10cm Ground Sample Distance (GSD) geospatial data with a 3km swathwidth at a 12,000 ft Above Ground Level (AGL) by a single Cessna flypass.
