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!

MTi-7 Alpha-1

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.
