The automatic landing guidance technology which meets the CAT III standard is the key technology to realize all-weather accurate landing, and it is an effective measure to reduce the accident rate in approach and landing stage. This paper proposed a generation of guidance errors and guidance instructions for automatic landing based on GPS-Aided ILS. Firstly, the glide path was defined by key points, and the mathematical description of the glide path was given in the form of vector. Then, a landing guidance errors calculation algorithm based on the spatial geometric relationship and a variable gain guidance instructions generation method based on the distance strategy were proposed. Finally, five hundred times stochastic simulations were conducted to evaluate the proposed guidance law under the condition of wind and sensors error disturbance, with the flight technical error, angle of localizer deviation and angle of glide slope deviation as indexes. It can be drawn from the results that the landing accuracy of the aircraft guided by the guidance algorithm given in this paper can meet the CAT III standard.
