A new quartz-based inertial measurement unit (IMU) combines lower cost and high accuracy for industrial applications ranging from agricultural and construction machinery to medical and military systems.
Introduced at the Sensors Expo last week, the new IMU is said to be about 100 times more accurate than the low-cost silicon IMUs employed in consumer products. At the same time, it’s expected to be a fraction of the cost of conventional fiber optic-based IMUs commonly used in aerospace and military applications.
