FIELD: radio engineering. ^ SUBSTANCE: Doppler route system (RS) includes a Doppler velocity sensor (DVS), a mechanical velocity sensor, a motion simulator, an output signal counter, a device for storing the length of the measured section, a calibration route accumulation device, a pulse "price" computer, a multiplier and a pulse "price" storage device. The system includes a counter, two trigger circuits, a calibrated route accumulator, an indicator and a calibration launching unit. ^ EFFECT: higher labour productivity and less expenses on monitoring working condition of the Doppler velocity sensor or route system. ^ 2 dwg |
