Inertia-Link® is a high-performance Inertial Measurement Unit and Vertical Gyro utilizing miniature MEMS sensor technology. It combines a triaxial accelerometer, triaxial gyro, temperature sensors, and an on-board processor running a sophisticated sensor fusion algorithm.
Inertia-Link® offers a range of output data quantities from fully calibrated inertial measurements (acceleration & angular rate or deltaAngle & deltaVelocity vectors) to computed orientation estimates (pitch & roll or rotation matrix). All quantities are fully temperature compensated and corrected for sensor misalignment. The angular rate quantities are further corrected for G-sensitivity and scale factor non-linearity to third order.
Inertia-Link's communications interface hardware is contained in a separable module, and can therefore be easily customized. Currently available interface modules include USB 2.0, RS232 and RS422. An OEM version is available without the communications interface enabling the sensor to be integrated directly into a host system's circuitboard, providing a very compact sensing solution.
The 3DM-GX2® Software Development Kit (SDK) provides application builders with robust protocols and source code samples to operate the Inertia-Link® and 3DM-GX2® orientation sensors. The SDK includes a complete Data Communications Protocol manual, a detailed Users manual, ANSI C Implementation and API. Sample applications demonstrating many protocol commands are provided with fully-commented source code for Microsoft® Visual Studio C++ 2003/2008 Express, LabVIEW® 7.1.1, Microsoft® Visual Studio Visual Basic 2005 and Microsoft® Visual Basic 6.0.
