Abstract. Bochum University of Applied Sciences (HS BO) is currently involved in an UAV project, whose fundamental developments are the result of an internet community. The MikroKopter system, being built by the laboratory, is a manually and autonomous flying platform. With regard to the implementation of an autonomous flight the MikroKopter is equipped with appropriate sensors for the flight control. The interaction of these components allows horizontal and vertical stabilized positioning of the system, as well as the return to the launch site. Using these positioning data a stabilization and orientation of the camera occurs, followed by a manual or automatically triggering of the camera to the predetermined positions. All flight data is completely recorded and can be evaluated at a later date.
Investigations to the quality of navigation data are presented. Based on different flights at the Bochum test field, combined with the use of alternative navigation sensors, an evaluation of the standard components of the MikroKopter system occurs. Another focus is given by efforts to optimize the control, stabilization and orientation of the camera.
