Patent Number Title Of Patent Date Issued
4151529 Radio beacon for aerial navigation system April 24, 1979
An air-navigational beacon, designed to simulate an imaginary circular ben with a multiplicity of pairs of diametrically opposite dipoles excited in cyclic succession, comprises an array of stationary dipole pairs disposed along lines parallel to a given direction. The spacing of th
4042929 Helicopter navigation system August 16, 1977
In a system for use in helicopter navigation antennas are carried at the e ends of each of the blades of the rotor of the helicopter. Radio waves transmitted by a beacon at a known location on the ground are received by the antennas and phase modulated by their rotation. On the rotor th
4019184 Direction-finding method and system April 19, 1977
High-frequency waves transmitted by a rotating antenna array at a ground tion are intercepted by an airborne receiver for photoelectric evaluation by one or more discs whose light transmissivity, by translumination or reflection, varies periodically according to a sinusoidal law in one
