Land Vehicle POS iVM-800 Inertial/ GNSS/ DMI ALL IN One Solution
GPS positioning in urban canyons, forest, or tunnel has always been challenging. By taking the best of complementary technologies, VMSENS Land Solution provides accurate positioning in a costeffective package.
iVM-800 is an inertial navigation systems based on the robust and cost-effective tactical grade MEMS technology. In land applications, GPS signal may be disrupted. The combination of VMSENS Inertial Navigation System with complementary technologies such as wheel speed sensor and RTK GNSS is the key to provide smooth vehicle positioning , even in urban canyons, forest, tunnel, etc. To save both time and money, we have tested and selected the best equipment to build a cost-effective and all-in-one package – iVM-800 Solution.

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.
