Miniature inertial navigation system Xsens MTi-7

lightweightbased on external GPS datahigh-accuracy

The MTi-7 is a self-contained GNSS/INS (Global Navigation Satellite System/inertial navigation system) with advanced sensor fusion algorithms. Self-contained Self-contained with advanced sensor fusion algorithms, the MTi-7 is a GNSS/INS (Global Navigation Satellite System/inertial navigation system) and can synchronize the inputs from its on-board accelerometer, gyroscope, and magnetometer with the data from an external GNSS receiver. Real-time data stream 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). Smallest industrial grade form factor As part of the MTi 1-series, it is among the smallest of its kind available, with each module measuring only 12.1 × 12.1 mm and weighing <1 g.
