DIFFERENTIAL GPS: EFFICIENT TOOL IN PHOTOGRAMMETRY

Research is reported which attempted to establish the attainable accuracy for an airborne dynamic GPS (Global Positioning System)-positioning system, and to establish the attainable reduction of ground control by introducing GPS camera positions in a photogrammetric block adjustment. This paper presents the results of the first part of the project and discusses the attainable accuracy for the GPS positions. The results of the study demonstrate that relative position accuracies better than 10 cm can be obtained for airborne kinematic applications using differential GPS techniques. It is expected that there will be substantial reduction in the attainable reduction of ground control when integrating the GPS observations in the photogrammetric adjustment. This will make differential GPS an efficent tool in the photogrammetric mapping process.
