COMPENSATION ACCELEROMETER Russian patent published in 2009 - IPC G01P15/13 

FIELD: measurements.

SUBSTANCE: invention relates to measurements and is designed to be used in compensation-type instruments furnished with a discrete output and incorporated with the navigation, stabilisation and guidance systems. In compliance with proposed invention, the compensation accelerometer incorporates additionally local positive and negative feedback, negative integrating feedback with smoothing filter. Note that the comparator output is connected to one of inputs of the second adder to allow stabilising local feedback circuit parameters. Note also that, applying integrating amplifier with the negative feedback circuit allows producing compensation accelerometer with astatism per departure.

EFFECT: higher accuracy of measurement, widened bandpass.
