An azimuth directional synchro output is provided for a gyroscopic compass, the compass consisting of a pendulous gyrosphere floating within a spherical cavity containing an electrically conductive fluid. By forming one electrode that carries power through the fluid to spin the gyroscope rotor as a band of sinusoidally varying width, four cooperating electrodes equally spaced about the instrument case supply azimuth position data to excite a selsyn data transmitter system. The currents collected by the four cooperating electrodes are proportional to the varying resistances of the respective fluid paths. They generate a vector field within the selsyn system which establishes outputs representing true azimuth bearing within the three selsyn output leads. |
