    摘要: An all solid state gyromagnetic compass system operable in the slaved, compass and free gyro modes wherein magnetic compass error rates, fast or slow slaving rates, gyro drift rates, earth's rate and set heading rates are all produced by means of a solid state analog angle rate generator. This generator includes a dual slope integrator responsive to scaled d.c. voltages representing the required rates and which generate shaped sine and cosine control signals therefrom for the various system modes having constant amplitudes and variable frequency representing the required rates. The system outputs are provided in standard three wire synchro format for interfacing with any utilization system requiring conventional slaved gyromagnetic compass data, magnetic compass data or free gyro data.

    摘要: A multiplexing apparatus for outputting selected input signals utilizes input transistors coupled between input sources and diodes. A first set of switching transistors, coupled to the input transistors and the diodes, blocks the outputting of nonselected input signals by applying a predetermined voltage to the anodes of corresponding diodes. A second set of switching transistors, coupled to the input transistors and the diodes, permits the outputting of selected input signals on the emitters of output transistors coupled to the diodes, by applying current to the emitters of corresponding input transistors, and the anodes of corresponding diodes.
