Inertial Measurement Unit ADIS16488 Small Size And High Overload
Resistance IMU
IMU16488B is a domestic inertial measurement unit with high
performance, small size and high overload resistance.
The gyro bias stability is 1.2 °/H (Allan) and the accelerometer
bias stability is 50 µg (Allan). This series of products adopt
high-precision MEMS inertial
devices, which have high reliability and high robustness, and can
accurately measure the angular velocity and acceleration
information of moving carriers in harsh environments.
