murata env-05h vibrating gyroscope 角速度传感器 陀螺仪







the Murata Gyrostar [Murata] model
ENV-05H (see Fig. 1). The Gyrostar is a piezoelectric
vibrating gyroscope with analog voltage output that
varies linearly with the measured rate of rotation. connection
to a computer. The drift rate we measured in
practice was 3 to 15E/min (similar to the drift observed
by [Barshan and Durrant-Whyte, 1995] for
their Gyrostar sensor). We will assume an average
drift rate of 10E/min = 0.166E/s
