3DM-GX3® -15 -- Product no longer stocked – limited availability
The 3DM-GX3® -15 is a high-performance, miniature Inertial Measurement Unit and Vertical Gyro, utilizing MEMS sensor technology. It combines a triaxial accelerometer, triaxial gyro, temperature sensors, and an on-board processor running a sophisticated sensor fusion algorithm to provide static and dynamic orientation, and inertial measurements.
The 3DM-GX3® -15 offers a range of fully calibrated inertial measurements including acceleration, angular rate, deltaTheta, and deltaVelocity vectors. It can also output computed orientation estimates including Euler angles (pitch and roll), rotation matrix and quaternion. All quantities are fully temperature compensated and are mathematically aligned to an orthogonal coordinate system. The angular rate quantities are further corrected for g-sensitivity and scale factor non-linearity to third order. The 3DM-GX3® -15 architecture has been carefully designed to substantially eliminate common sources of error such as sensitivity to supply voltage variations. On-board coning and sculling compensation allows for use of lower data output rates while maintaining performance of a fast internal sampling rate. For those users, integrators or OEMs who develop their own orientation and navigation applications, the 3DM-GX3® -15 is shipped with a complete Data Communications Protocol guide that provides access to the powerful LORD MicroStrain® Inertial Packet Protocol (MIP). Applications of your own design can readily be developed in any coding language and on any computing platform including microprocessors. The 3DM-GX3® -15 is initially sold as a starter kit consisting of an IMU module, RS-232 or USB communication and power cable, software CD, user manual, and quick start guide.
