Description

The MS-IMU3025 MEMS Inertial Measurement Unit delivers standout inertial performance in an ultra-compact package. The tactical gyro bias instability and sub-seven micro-g accelerometer bias instability supply ample inertial performance to support a wide range of applications from inertial navigation and control to precision platform stabilization. User configurable options allow the IMU to be tuned to your application with configurable bandwidth, sample rate, gyro ranges, accel ranges, 1 PPS input and other measurement parameters. The accelerometer dynamic range configurability spans a range from ±2g up to ±40g that enables applications from land navigation to catapult-launched drone systems. The IMU provides all these features in a package that only measures 1.1 x 1.1 x 0.45 inches with a mass of only 17.9 grams. The MS-IMU3025’s combination of inertial performance, size, and reconfigurability surpass all IMUs in the market.
