SYSTEM FOR POSITIONING AND ORIENTATION OF AN AIRCRAFT WITH RESPECT TO A REFERENCE BEACON USING RADIO WAVES

System for positioning and orientation in three dimensions of an aircraft (A) with respect to a reference beacon (B) by radio waves, based on the calculation by a Central Processing Unit (CPU) of the delay differences between the signals of input to said Central Processing Unit (CPU). The reference beacon (B) transmits several pseudorandom codes that are detected in the aircraft (A) by correlation with another version of the same codes generated at a slightly different frequency, which causes a slowing effect of the received signal that enables that the Central Processing Unit (CPU) has time to detect it.
