This drone comprises a sensor for measuring representative data, comprising at least one measurement cell that is open to the atmosphere, at least a first laser source configured to inject, into the measurement cell, a first laser beam at a first wavelength characteristic of a first gas to be detected and a second laser source configured to inject, into the measurement cell, a second laser beam at a second wavelength characteristic of a second gas to be detected. The measuring sensor comprises a detector common to the two laser sources, said detector being configured to detect a first measurement signal originating from the measurement cell and resulting from injection of the first laser beam into the measurement cell and a second measurement signal originating from the measurement cell and resulting from injection of the second laser beam into the measurement cell.
