#MEMS: "ADI debuts tactical-grade MEMS"

A new tactical-grade inertial-measurement unit (IMU) from Analog Devices Inc. achieves performance rivaling expensive, bulky fiber-optic based units by virtue of micro-electro-mechanical system (MEMS) chips that are almost eight-times smaller and over 10-times lighter, according to the company.



The first two members of the new tactical-grade MEMS family, include a 10-degree-of-freedom IMU that combines a three-axis accelerometer, a three-axis gyroscope, a three-axis magnetometer, and a barometric pressure sensor to determine altitude—the 10th dimension. Drift is 6 degrees per hour for a unit that consumes just 0.7 watts.
