Abstract:
A rate measuring system for providing velocity signals, as desired, and displacement signals, including at least one accelerometer for providing an output voltage proportional to an acceleration input, amplifying means having an adjustable voltage gain for amplifying the output voltage from the accelerometer, means for integrating the amplifier output voltage to provide an output voltage proportional to velocity, means for comparing the output voltage proportional to the acceleration input and the output voltage proportional to velocity with predetermined voltage reference levels to provide an output signal when these signals are nominally zero, and means for shorting out the integrating means in response to a signal from the comparison means to provide a nominal zero velocity output.
