Description
The MS-IMU3030 Inertial Measurement Unit delivers unmatched low drift performance in an ultra-compact aluminum package. The IMU contains triaxial MEMS gyros, accelerometers and magnetometers that are extensively tested and calibrated over the full operational temperature range to ensure the highest performance and robust operation. The gyro bias stability of 0.55 degrees per hour and accel bias stability of 2.9 micro g supply ample performance to support a range of applications from UAS navigation and control to platform stabilization. The inertial measurement unit’s accelerometer provides more application flexibility with a 40 g dynamic range option. User configurable options allow the IMU to be tuned to your application with configurable bandwidth, sample rate, dynamic ranges, 1 PPS input and other measurement parameters. The blend of miniature size and high performance in the MS-IMU3030 IMU is unparalleled in the low drift IMU market.
