Why Choose the MTi 1-Series
12×12 mm of integrated sensor fusion
Smallest form factor in the market: 12×12 mm Surface Mount Device. Integrated sensor fusion, thus no external processing needed!

High Performance in a Small Footprint
Higher accuracy than any other ultra-compact module in the market. Strong magnetic immunity out of the box, with advanced recalibration tools for demanding applications. Every sensor is individually factory-calibrated.
Scalable & Suitable for High-Volume
Very cost-efficient for large deployments. Factory calibration ensures consistent and repeatable performance at scale.
Fast Evaluation & Easy Integration
Development Kit & SDK readily available for quick testing. Plug-and-play integration possible through Xsens partners' solutions.
Multiple Functionalities
The MTi 1-Series comes in 5 different versions (IMU, VRU, AHRS, GNSS/INS. GNSS/INS + RTK) to give you exactly the performance you need.

Series Lineup
MTi-1
IMU (Inertial Measurement Unit). Provides calibrated data on the rate of turn, the acceleration and the magnetic field – all in 3D.
More about the MTi-1
MTi-2
VRU (Vertical Reference Unit). Sensor fusion algorithm computes 3D orientation data based on a gravity reference frame: drift-free roll, pitch, and accurate, unreferenced yaw.
More about the MTi-2
MTi-3
AHRS (Attitude and Heading Reference System). Delivers true-north-referenced yaw, or heading.
More about the MTi-3
MTi-7
GNSS/INS (Global Navigation Satellite System/Inertial Navigation System). Can synchronize the inputs from its on-board accelerometer, gyroscope, and magnetometer with the data from an external GNSS receiver.
More about the MTi-7
MTi-8
GNSS/INS + RTK (Real-Time Kinematic). Centimeter level accuracy in the smallest RTK-enhanced module of its kind.
