Quartz gyro-sensor based inertial measurement unit from Epson Toyocom

Epson Toyocom has developed inertial measurement unit (IMU) based on QMEMS quartz gyro-sensors. This device integrates ±300 degrees per second triple gyroscopes on three axes and three ±3-G tri-axis accelerometers. This IMU is currently under development. This device is suggested for applications such as motion analysis and control, control of moving objects, navigation systems, platform stabilization and control and movement analysis.

The IMU features gyro bias instability less than 6 degrees per hour and angle random walk performance less than 0.24 degrees per ?hr. The IMU's instability and accuracy parameters are approximately 25% and 12.5% better than comparable IMUs available in the market, according to Epson Toyocom. The IMU shows bias-temperature stability less than 0.005 degree per second /°C) across the operating temperature range.

Epson Toyocom's QMEMS technology enables it to downsize the device package for easy assembly in lightweight applications and mobile systems. The IMU is suitable for a variety of applications in areas such as industrial system motion analysis and control, moving object control, and vibration control and stabilization.

Availability: Scheduled to sample in April 2011.
