Abstract

This paper reports the principle of an micro-machined gyroscope (angular rate sensor), whose output signal is fuse both roll rate and yaw rate two information. The output sine wave frequency is the rotating carrier roll rate, which is easily detected, but the amplitude depends on the roll rate and yaw rate. Otherwise, fabrication defects are always inevitably present, which gives rise to the scale factor of different gyroscope can not be identical. In order to solve these problems, a simple method is presented. The results show that the relationship between output signals and yaw rate is linearity and thus reduce the effect of the roll rate variety on the output signal. Further, different gyroscopes have the same scale factor.
