Analog Devices Introduces New Tactical Grade IMU

By Mike Ball / 31 Oct 2016

Analog Devices Tactical Grade IMUAnalog Devices, Inc. has announced the introduction of a new tactical grade Inertial Measurement Unit (IMU). The ADIS16490 IMU is designed for high-accuracy navigation, guidance, and positioning for applications ranging from aviation and unmanned systems to machine control and precision instrumentation.

The ADIS16490 IMU delivers:

  • Tactical grade in-run bias stability of 1.8 deg/hour and 3.6 micro-g
  • Lowest angular random walk (0.09 deg/root-hr) and velocity random walk (0.008 m/sec/root-hr)
  • Factory calibration on every device, across temperature, providing extremely tight tempcos of 24 ppm/degree C (gyro) and 16 ppm/degree C (accelerometer)
  • High level of immunity to vibration (0.005 deg/sec/g) and shock (2000 g) over extended temperature range

The ADIS16490 represents Analog Devices’ most advanced IMU, leveraging years of system-level experience and ADI’s best performing angular rate and linear acceleration MEMS cores combined with precision calibration, sensor filtering, and fusion. As a result of this advanced level of integration, engineers now have a product that offers low Gyro Angular Random Walk and Accelerometer Velocity Random Walk to help eliminate jitter in stabilization feedback loops, as well as maintain low positional drift in navigation applications where a carefully balanced combination of low noise, tight alignment, vibration immunity, and wide bandwidth (480 Hz Gyro, 750 Hz Accel) provide a low total error for challenging system implementations.

ADI also plans to offer two further variants of the ADIS16490 IMU, the ADIS16495 and ADIS16497, which will offer greater dynamic range options, meaning improved design flexibility and broader application reach for system developers.
