Zusammenfassung:Said drone (10) comprises a sensor (40) for measuring representative data, comprising at least one measuring cell open to the atmosphere, at least one first laser source able to inject, into the measuring cell, a first laser beam to a first wavelength characteristic of a first gas to be detected and a second laser source able to inject, into the measuring cell, a second laser beam at a second wavelength characteristic of a second gas to be detected. The measuring sensor (40) comprises a detector common to the two laser sources able to pick up a first measuring signal from the measuring cell resulting from the injection of the first laser beam into the measuring cell and a second measuring signal from the measuring cell resulting from the injection of the second laser beam into the measuring cell.
