Gyro-Enhanced AHRS (iVM-x)

The iVM-x is a high performance, miniature, gyro-enhanced Attitude and Heading Reference System (AHRS) / motion tracking system. Its internal low-power signal processor provides a quaternion-based iMTFusion™ Algorithm to output drift-free 3D orientation as well as calibrated 3D acceleration, 3D rate of turn and 3D earth-magnetic field data.

VMSENS has optimizing the Extended Kalman Filter for different applications, which can be used in a wide range of applications. To application specific requirements, the fusion algorithm supports different filter settings.

The iVM-x can be widely used for stabilization and control of cameras, antenna robots, vehicles and other (un)manned equipment and also other field where high-performance 3D orientation measuring is needed.

VMSENS Development Kit

with the VMSENS SDK, your preferred solution is easy and fast to realize, with the demo source code, you will have your measurement unit up and running in just a few minutes to start your first R&D.

VMSENS Software Development Kit (SDK) contains:

VMSENS Explorer
The VMSENS Explorer is graphical interfaced software to be used with the VMSENS devices, by using the VMSENS Explorer, user can get, save and view the real-time inertial motion data easily, the data is shown via friendly graphical component to the you.

IMT™ Inertial Motion Tracking
The inertial Motion Tracking Package(iMT™ )is a collection of functions used in the inertial field by the VMSENS, by exploring the iMT™ , users can find useful functions needed in inertial field.
The iMT components are strictly tests in applications, the long term test ensure that your software quality, to minimize the uncertainty of the development procedure, to shorten time-to-market, we can support all source code level support.

The COM-Object and DLL API interface Development Tools
The VMSENS COM-Object and DLL API will help save time in interfacing in a reliable way with VMSENS devices in a Windows environment. Direct low level interfacing gives full control and maximum flexibility. The example code (C/C++, Excel (VBA) and Matlab/ Labview) can be easily extended to a user-specifc program.

High Performance
The VMSENS device uses multi-inertial sensors to estimate the orientation. The single used gyroscopes to calculate orientation, the drift is inevitable. To compensate for drift completely, the device corrects its orientation using the gravity and the earth magnetic field as reference vectors. The VMSENS iMTFusion™ Algorithm can cope with magnetic and accelerations, resulting in a reliable orientation estimate. Additionally, the VMSENS provided a magnetic field calibration routine to correct for hard and soft iron effects.
