APPLICATIONS OF THE GLOBAL POSITIONING SYSTEM IN AERIAL PHOTOGRAPHY (SATELLITE, PHOTOGRAMMETRY, SURVEYING, ORBIT MECHANICS)
Abstract
The applications of the Global Positioning System (GPS) in aerial photography is investigated by a simulation approach. The airborne system proposed in this study consists mainly of a precise clock, a digital recording device, number of GPS satellite receivers, and a metric camera. The GPS data processing is presented in Chapter 4, where the carrier phase difference is used. A post-mission smoothing to the aircraft flight-path is developed in Chapter 5. The flight-path is used as a generator of control points. Therefore, the need for ground control is dramatically reduced. In Chapter 6, the absolute orientation of the aerial camera is achieved by using three techniques. This simulation predicts an accuracy of 2 meters, if this kind of airborne system is designed.
