Gasflow style level posture sensor and angular velocity gyroscope assembled inertial sensor

The compensational loop consisting of a gasflow style angular velocity gyroscope and gasflow level posture sensor is proposed to improve the signal of gasflow style tilt. This compensational loop could remove acceleration interfere from the signal of tilt. This assembled gasflow type inertial sensor not only measures static state angular, but also restrains the acceleration which interferes the output signal of level posture sensor in dynamic situations. Therefore, the precision of outputs signal increases greatly. Moreover, the output signal includes the angle velocity signal.
