Experiences on operational GPS/inertial system calibration in airborne photogrammetry
نویسنده
چکیده
Overall system calibration is one limiting factor in direct georeferencing. Within this context the stability of system calibration over longer time periods and the influence of additional self-calibration is of special interest. The investigations presented are based on test material from a real flight test, where a calibration field was flown several times within a two month period using the same system installation. First statements on operational calibration and long term stability are feasible, which are especially important from practical aspects.
