| Abstract: | The gyroscope is the important sensor of the vehicle navigation system,which can measure the vehicle's course,and its pre- cision will directly determine the navigation system's precision.According to this,this paper adopts the power supply block with high stabil- ity and hardware filtering circuit technique in order to increase the stability of gyro's power supply and the signal-noise-ratio of the output signal.At the same time,on the basis of analyzing the elements of gyro signal,this paper finishes the automatic update of gyro's zero volt- age with high precision to increase the gyro's precision by study deeply the gyro's zero voltage.The experimental results show that this scheme is feasible. |
