About the MTi-7

The MTi-7 is a self-contained GNSS/INS (Global Navigation Satellite System/Inertial Navigation System)The MTi-7 uses advanced sensor fusion algorithms developed by Xsens to synchronize the inputs from the module’s on-board accelerometer, gyroscope and magnetometer with the data from an external GNSS receiver and/or barometer. The raw sensor signals are combined, and processed at a high data rate of 100 Hz, to produce a real-time data stream with the device’s 3D position, velocity and orientation (roll, pitch and yaw).  

As a member of the MTi 1-series, the MTi-7 is the smallest motion tracking module of its kind (12.1x12.1mm). It also stands out because of its easy integration, low cost, robustness and strapdown integration algorithm. Suitable for a wide range of (embedded) applications, the MTi-7 relieves you of the task of designing, integrating and maintaining gyroscopes, accelerometers and other sensors for GNSS/INS functionality.
