摘　　要：MEMS陀螺仪作为现代自主导航设备的重要组成部分,是姿态监测和导航控制非常重要的一环。针对模拟输出的MEMS陀螺仪信号,以ADXRS645的输出信号为例,在分析陀螺仪的模拟输出方式的基础上,详细论证通过外部电路调节陀螺仪量程的可能性,并设计相关电路,利用三轴位置速率摇摆温控转台进行试验论证。实验结果表明,设计的陀螺仪量程调节电路正确有效,具有一定的工程应用价值。As an important part of modern autonomous navigation equipment,MEMS gyroscope is a very important part of attitude monitoring and navigation control.This article mainly focuses on the analog output MEMS gyroscope signal.Taking the output signal of ADXRS645 as an example,on the basis of analyzing the analog output mode of the gyroscope,the possibility of adjusting the range of the gyroscope through an external circuit is demonstrated in detail,and the relevant design is designed.The circuit uses a three-axis position and speed swing temperature control turntable for experimental demonstration.Experimental results show that the designed gyro range adjustment circuit is correct and effective,and has certain engineering application value.
