The typical airborne remote sensing measurements conducted by the Helsinki University of Technology laboratory of space technology require very precise navigation over the selected measurement sites. This means that both system performance as far as positioning is concerned and the actual flight track of the aircraft has to be within 10 meters. To meet these requirements, a custom made navigation system was designed and installed in the SHORT SC7 Skyvan research aircraft of the Helsinki University of Technology. The system is based on the Finnish national Differential GPS network providing positioning accuracy within a few meters within Finland. For pilot guidance, a graphical user interface with mission specific software is used to give the pilots an overview of the relative position and orientation to the measurement target. In addition, the system is used to synchronize the scientific instruments and record the actual flight track. 2 refs., 2 figs.
