Analog Devices’ 10-Degrees-of-Freedom MEMS iSensor® IMU Simplifies Designs for Unmanned Vehicle and First Responder Navigation

Analog Devices, Inc., (ADI) released for general availability today the ADIS16407 iSensor® IMU (inertial measurement unit) which integrates a tri-axis gyroscope, tri-axis accelerometer, tri-axis magnetometer and a pressure sensor into a single package. Each sensor in the ADIS16407 combines ADI’s industry-leading iMEMS® technology and signal conditioning expertise to optimize the IMU’s 10- DoF (degrees-of-freedom) dynamic performance. Every IMU is factory calibrated for sensitivity, bias, alignment, and temperature. As a result, each sensor has its own dynamic compensation formulas, maximizing accuracy of sensor measurements.

“Emergency first responders, unmanned vehicles, and precision autonomous instruments often require the merging of multiple sensors to accurately track location in office buildings, warehouses, tunnels, caves, mines, ‘urban canyons’ and other GPS-denied environments,” said Bob Scannell, iSensor business development manager, MEMS/Sensors Technology Group, Analog Devices. “All existing 10-DoF IMUs for these applications are significantly larger, with less factory calibration, and do not adequately address the price-performance requirements. The ADIS16407 combines all of these sensors in a single package, fully integrated and calibrated at the factory, at a low system price.”

Navigation technology used in first responder or unmanned vehicles not only require multiple axes of sensing, precisely aligned, but also cross integrated to discern tracking/location in dynamic environments. Where no one single sensor provides the required precision, the solution involves merging multiple sensor types with a deep knowledge of the dynamics of the application environment. The ADIS16407 addresses a major portion of this integration effort by combining all necessary sensors in a single product with a simple interface, and full factory calibration, leaving the system designer more time to focus on system dynamics/filtering specific to their application.
