항공촬영을 위한 무인 비행선의 경로 추종 비행시험

General unmanned airship for aviation photograph is controlled by a pilot on the ground. However, if the mission area located far from the pilot or in the area hard to be approach, it is required to do pathfollowing autonomous flight. In this paper, single path, multi-path following, one point continuation turn, and LOS guidance mode were designed and verified requirements by doing flight test. In order to do flight test, an unmanned airship autonomous system was composed of an airship, FCC(Flight Control Computer), GCS(Ground Control System), Autopilot program, GUI(Graphic User Interface) based analysis program for the analysis of flight test result, and Test Log Sheet for the management of flight test data.
