China alternative ADIS16488BMLZ –
High-Performance Inertial Measurement Unit IMU16488
Different from quartz accelerometer and fiber optic gyroscope composed of IMU/INS, IMU16488 Inertial Measurement Unit is a high-performance tactical grade MEMS Inertial Measurement Unit, it is composed of 2°/h (Allan) bias stability MEMS gyroscope and 0.1mg (Allan) bias stability MEMS accelerometer, which can output precise 3-axis outputs of angular rate, 3 axis acceleration data, 3 axis magnetometer data, and barometer data, etc.
IMU16488 IMU adopts the latest capacitive technology and advanced MEMS components, which reduces the cost deeply. The system enjoys small size and lightweight, it features Mil-Standard reliability and is housed in an ultra-durable and compact aluminum housing.
The IMU16488 is packaged in a module that is approximately 47mm × 44mm × 14mm and includes a standard connector interface, totally the same size as the original ADIS16488BMLZ.
