Flying vehicle guiding system and associated guiding method

A flying vehicle guiding system (1), which comprises a remotely controllable flying vehicle system (2), a surveying instrument (3) able to measure distance, angle, and track, and a ground base station (4) for controlling flight of the flying vehicle system based on measuring results by the surveying instrument. The flying vehicle system (2) has a retro-reflector (9) constituting an object to be measured. The surveying instrument (3) has a non-prism surveying function for performing distance measurement and angle measurement without a retro-reflector, a prism surveying function for performing distance measurement and angle measurement with respect to the retro-reflector (9), and a tracking function for tracking the retro-reflector (9) and for performing distance measurement and angle measurement. The surveying instrument (3) performs non-prism measurement on a scheduled flight area, the ground base station (4) sets a safe flight area based on the results of the non-prism measurement, and controls the flying vehicle system so that it flies in the safe flight area based on the results of the tracking measurement by the surveying instrument.
