The MTi-G is a small size and low weight measurement unit, excellent for control and navigation of (un)manned systems and other objects.

The MTi-G is a GPS aided MEMS based Inertial Measurement Unit (IMU) and static pressure sensor. It delivers unprecedented performance for its size, weight, cost and low complexity in use. The MTi-G overcomes typical IMU and AHRS challenges faced in e.g. aerospace and automotive applications.

The design of the MTi-G is flexible, providing a wide range of output modes and advanced settings for specific usage scenarios, optimizing the sensor fusion algorithm routine for different applications.

The MTi-G has an onboard Attitude and Heading Reference System (AHRS) and Navigation processor. This low-power Digital Signal Processor runs a real-time Xsens sensor fusion algorithm, providing drift-free, GPS-enhanced, 3D orientation data.

Additionally the MTi-G provides inertial and barometric enhanced 3D position and velocity data at a higher update rate than possible with a typical GPS receiver.

High performance

The MTi-G is a combination of a MEMS IMU, GPS and barometer. Yet, the MTi-G is more than just a sensor assembly. The IMU, GPS and barometric information is blended together in Xsens’ sensor fusion algorithm to estimate the most accurate orientation and position possible. Because of this fusion, the output is more accurate than the output from the IMU or GPS receiver only. For example, the MTi-G copes with transient accelerations; a typical error source for any AHRS using the gravity as its reference estimating roll and pitch. The loose coupling works both sides: double-integrating the accelerometers for short periods, the MTi-G is able to calculate position and velocity even during short GPS outages. There are several more corrections realized to aid the IMU functionality and to enhance the GPS measurements.

User friendliness

The MTi-G is a sensor which can be used in a wide range of applications. Because of the specific requirements for all these applications, the MTi-G uses different filter settings and constraints, implemented in scenarios. Among others, there are scenarios for use in automotive and aerospace applications. The accompanied MT manager software enables.
