1. A method of guiding an aircraft in the approach phase comprising the steps consisting for the aircraft in:

  • receiving information on a predefined approach path, this information being contained in a message M4 originating from a ground beacon transmitting on a same transmission channel as that of a beacon of a GBAS type positioning accuracy augmentation system;

    receiving differential positioning satellite radio signals, and correction information from the satellite radio signals in the form of a message M1

    originating from a ground central station of an SBAS type positioning accuracy augmentation system, via geostationary satellites of this augmentation system; and

    calculating a corrected position based on positioning signals and correction information, calculating an elevation and horizontal guidance deviation of the aircraft relative to the predefined approach path, based on the corrected position and information on the predefined approach path.
