An industry-leading development platform

Icon of two arrows making a circle

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.


Data stream
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).
