ABSTRACT In accordance with a laser-optical navigation method a rotationally pulsed beam of light in the form of a vertical disc is emitted from a sensor unit. Light reflected from reflectors is registered by the sensor unit and is computer processed for position determination purposes. In a device designed to perform the method the sensor unit comprises means which are arranged to emit a rotationally pulsed beam of light in the form of a vertical disc. The device also comprises means for measuring the elevation angle position of the device and an angle transducer for determination of the lateral angle position. A first computer effects an image analysis operation and a second computer executes the navigation determination calculations on the basis of information received from the first computer. Fig. 3 13
