MS-IMU3050 MEMS Inertial Measurement Unit

Quick Overview

The MS-IMU3050 is a high performance MEMS Inertial Measurement Unit (IMU). The MS-IMU3050 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. Gyro Bias Stability of 0.40 °/h, Accelerometer Bias Stability of 40 µg. The MS-IMU3050 IMU provides all this in a package that measures 40.6 x 45.7 x 25mm with a mass of only 60 grams.

The coordinate system for the MS-IMU3050 follows the right hand rule convention. As an example, with the inertial measurement unit pictured in Figure 2, if the Z axis is pointed straight UP away from the earth, it will produce 0 g for the X and Y axes and a positive 1 g for the Z axis. A counterclockwise rotation of the IMU about any of the depicted axis will produce a positive angular rate output for the corresponding axis. The magnetometer sign convention produces a positive output on the corresponding axis aligned in the North direction with the IMU bottom parallel and facing the Earth’s surface.

The gyro bias stability of 0.33 degree per hour and accelerometer bias stability of 21 micro g supply ample inertial performance to support a range of applications from Unmanned Aircraft System (UAS) navigation or positioning and stablisation applications. User configurable options allow the IMU to be tuned to your application.

The MS-IMU3050 is contained in an ultra-durable MIC-6 alloy housing with a MIL-A-8625 coating and military standard interface connector. Mounting of the IMU is achieved through four captive socket head cap screws. The mounting surface of the mechanical interface is flat to within one one-thousandths of an inch. The dimensions above are only an overview of the housing, detailed mechanical drawings in Imperial and Metric units are available on request.
