Airborne Integrated Mapping System: Positioning Component

Dorota A. Grejner-Brzezinska

Abstract:	The Center for Mapping at The Ohio State University is currently developing a fully digital Airborne Integrated Mapping System (AIMS) for large-scale mapping and other precise positioning applications. AIMS will be installed in an aerial platform and will incorporate state- of-the-art positioning (differential GPS integrated with INS) and imaging (CCD, SAR) technologies. The project’s goal is to develop a low-cost hardware prototype that acquires position and orientation of an aerial platform with accuracy of 4-7 cm and below 10 arcsec, respectively, over long baselines, and performs essential processing of digital imagery in real-time and in post-processing mode. The potential applications include large-scale topographic mapping, military reconnaissance, real-time target tracking, corridor surveys of the transportation infrastructures, gas, electric and telecommunication networks, drug interdiction efforts, and emergency response deployment. A tightly integrated Global Positioning System and high-accuracy Inertial Navigation System (GPS/INS) provide orientation and position of the aerial platform. A single Kalman filter optimally estimates position, velocity, and attitude parameters, as well as errors in GPS and INS measurements. This paper presents the AIMS architecture and implementation, with special emphasis on the positioning component of the system, together with airborne test results.
