The paper presents results of the bridge crane rail (CR) geometry determination with automated measurement system. The system consists of geodetic (robot station) and nongeodetic (electronic measurement systems) technologies. The robot station Leica TCA1101 (equipped with function LOCK and ATR), the three standard prisms for orientation and notebook are located on the floor and create the static part of the measurement system. Nongeodetic technologies - amplifier HBM Spider8, inductive transducers HBM WA100, terminal and connecting cables and 360° prism are attached to the moved part of the measurement system, which is drifted by a crane. Position of the 360° prism is determined by the 3D polar method from one or several instrument positions. All measured data from robot station are registered to the notebook. Two electronic (inductive) transducers are fixed to the moved part of the measurement system and determine the relative position of the rail to the prism centre in both vertical and transverse direction. The accuracy of the rail position depends on the accuracy of the prism position, of the system geometry and determination of electronic sensor position changes. The paper included the development of the system and the results of first application at 240 m long bridge crane which is situated in Power Station Gabčíkovo (Slovakia).
