Inertial Measurement Unit ADIS16488 Small Size And High Overload Resistance IMU
Low Bias Stability IMU 16488 High Precision MEMS Inertial Devices With Built In GPS / BD Dual Mode Satellite R
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). It can be used for precise
navigation, control and dynamic measurement of weapons. 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.
Product features:
※ High Precision MEMS Inertial Navigation ※ GPS/BD Dual Mode
※ Integrated navigation, AHRS, vertical gyro and other working modes
※ Support dynamic fast alignment ※ High bandwidth, 400Hz data update rate
※ External interface: 1-channel SPI and 1-channel UART
※ Support multiple external sensor combinations (odometer/DVL)
※ Small size, light weight ※ Strong and reliable
※ Fully compatible with a foreign 10-Dof inertial measurement system
