9-Axis MEMS IMU 0.3°/h Gyro Bias for Drone Flight Control & GNSS-Denied Navigation
The ADIS16488HA is a compact, lightweight MEMS IMU featuring a three-axis gyroscope and accelerometer, with measurement ranges of ±450°/s angular rate and ±20 g acceleration. With exceptional zero-bias instability of 0.3°/h for the gyro and 0.25 mg for the accelerometer, this unit delivers minimal random walk and 100-500 ppm scale factor linearity. Advanced temperature, misalignment, and nonlinear error compensation ensure reliable performance across an operating range of -45°C to 85°C. Featuring SPI communication at 8-15 MHz, 1.5 W power consumption, 250 Hz bandwidth, and 0.1% cross-coupling, this IMU is ideal for UAVs, robotics, industrial automation, mobile mapping, and precision navigation systems.
