Description

 

The iVM™-x is a high performance, miniature, gyro-enhanced motion tracking system (IMU/ VRU/ AHRS/ GPS-INS). 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.

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.  

 

High Light

l  Real-time computed attitude/heading and inertial dynamic data

l  High Effective VMSENS EKF sensor fusion

l  360º orientation referenced by gravity and earth magnetic field

l  MEMS base 3D gyroscopes, accelerometers and magnetometers integrated

l  On board data processor with real-time sensor fusion algorithm

l  Gyroscopes enable high-frequency orientation tracking

l  End to end software support

 

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.

 

Output

l  3D orientation Quaternion/ Euler/ DCM 

l  3D acceleration/ 3D rate of turn/ 3D magnetic field

l  Heave Sway and Surge

Software System Integration

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.

 

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-specific program.

 Low Level Communication Lib (For embedded systems) (optional)

VMSENS provided low-level C libraries for embedded developments to ease the development procedure on embedded systems.

Sample code

The VMSENS provide sample code of the development ways mentioned above, by reading the sample code and comments, unprofessional developers can developer the motion applications in a few minutes time.

VMSENS Motion Tracker Network Manager

The VMSENS Motion Tracker Network Manager is graphical interfaced software to be used with the VMSENS devices, by using the Motion Tracker Network Manager, 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 measuring field by the VMSENS, by exploring the iMT, users can find useful functions needed in the motion and attitude measuring field, also user can integrate these function components into their own systems quickly.

 

 

Application

Unmanned Vehicles control

  • Stabilization AUV/ROV/UUV
  • Orientation adjustment for equipment under water
  • Vehicle performance analyzing
  • Orientation measuring for unmanned vehicles 
  • GPS enhancements

The Inertial Navigation System (INS) is one of the most critical parts of an unnamed vehicle. VMSENS has developed reliable products to help you in the design of a miniature and powerful Navigation System. Due to its small size and high performance, a full featured Attitude and Heading Reference System (AHRS), is perfect to measure the orientation and the position of a miniature unmanned vehicles.

VMSENS AHRS products are fast responding can ensure stabilize the orientation and can also keep the heading in normal and abnormal situations.

 

Platform Stabilize

  • Antenna platform tracking
  • Camera platform

The VMSENS product is small enough for integration with most of the platforms where stabilizing is needed, such include cell base station antennas, radar systems, the satellite tracking antennas, the VMSENS provide product with fast response and high turning rate measuring range to track the platform in full 360 orientations, for Stabilizing the camera platform, the picture quality of the camera can be ensured.
