SYSTEM FOR CORRECTING GYROSTABILIZER OF MARINE GRAVIMETER Russian patent published in 2006 - IPC G01C19/54 G01V7/16 

FIELD: instrument engineering.

SUBSTANCE: system comprises accelerometer, integrator, amplifier, moment pickup, band filter-observer for extracting alternative component of the signal from the accelerometer with the Shuler frequency, comparator, transfer clamping circuit, control circuit, band filter-meter for extracting alternative component of the signal from the integrator with the Shuler frequency, and switch. The output of the accelerometer is connected with the first input of the integrator and with the input of the band filter-observer. The output of the integrator is connected with the input of the amplifier and with the input of the moment pickup of the gyroscope. The output of the band filter-observer is connected with the input of the comparator whose output is connected with the input of the transfer clamping circuit whose output is connected with the input of the control circuit whose second output is connected with the second input of the band filter-meter and with the second input of the band filter-observer whose first output is connecter with the first input of the switch whose second input is connected with the output of the band filter-meter. The output of the switch is connected with the second input of the integrator.

EFFECT: enhanced precision.
