MS-IMU3020 Inertial Measurement Unit

2-3 Weeks Del.

Quick Overview

The MS-IMU3020 is a low drift miniature Inertial Measurement Unit (IMU). The MS-IMU3020 contains triaxial gyros, accelerometers and magnetometers that are extensively tested and calibrated over the full operational temperature range to ensure optimal performance and robust operation. Gyro Bias Stability of 1.08 °/h, Accelerometer Bias Stability of 14.8 µg. The MS-IMU3020 IMU provides all this in a package that measures 28 x 28 x 10.5mm with a mass of only 20 grams.

The coordinate system for the MS-IMU3020 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 1 degree per hour and accelerometer bias stability of 15 micro g supply ample inertial performance to support a range of applications from Unmanned Aircraft System (UAS) navigation and control to pipeline inspection. User configurable options allow the IMU to be tuned to your application with configurable bandwidth, sample rate, gyro ranges, 1 PPS input and other measurement parameters.

The MS-IMU3020 is contained in a 6061-T6 Aluminium housing anodized to MIL-A-8625 standards. Mounting of the IMU is achieved through four 2-56 captive socket head cap screws while alignment is facilitated through two one sixteenth inch dowel pins. 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.
