The invention consists of an apparatus and a method for receiving satellite positioning signals. The apparatus comprises an antenna array comprising two antennas that can receive satellite positioning signals generated by at least one constellation of artificial satellites, and at least two phase shifters positioned downstream of said antennas. The outputs of said phase shifters are connected to each other by means of an output collector, which can be put in communication with a positioning device, and wherein the output collector constructive interference can be generated between the satellite positioning signals and/or disruptive interference can be generated between the reflections of said satellite positioning signals and/or between signals coming from sources located in positions other than those of the satellites of the said constellation of artificial satellites.
