摘要： The present invention relates to a gas pendulum inertial sensor, which is used in control technology field to detect pose measurement of motional body, such as ship craft and robot, wherein the inertial sensor main includes a gas pendulum angular velocity sensing element, a gas pendulum tilt sensing element and a signal process circuit, wherein the signal process circuit mainly comprises a bridge circuit, a amplify circuit, a filter circuit, and a SCM compensation circuit with a null position and sensitivity compensation program, a linearity and output compensation program, an acceleration interference offset subprogram, and an omnibearing tilt signal compensation program, whereby the SCM compensation circuit integral into a circuit board to replace a conventional hardware signal amplify circuit, a filter circuit and a compensation circuit. The gas pendulum inertial sensor is adapted to accurately measure not only an object's indication without interference from the acceleration, but also an object's indication with interference from the acceleration. The gas pendulum inertial sensor has some significant advantages like highly attack-resist ability, intensively vibrate-resist ability, quick response time, wide ranges of working temperature, well linearity, credibility, sensitivity and precision ability, compact capacity and lower cost.
