Xsens designs and develops Attitude and Heading Reference Systems (AHRS). In order to improve the performance of these AHRS systems an Inertial Navigation System (INS), which uses angular velocity and acceleration data from an Inertial Measurement Unit (IMU), can be used to compute a relative position over time. Because the INS provides a relative position with respect to an initial starting point, it will eventually drift from its true position quickly when no external reference is provided. Global Navigation Satellite System (GNSS) support can be included to provide this reference.
One of the first GNSS systems is the well-known American based Global Positioning System (GPS). Since GPS is not the only available network, the term GNSS is used to describe all the combined navigation networks globally. This term includes Russia’s GLONASS, China’s BeiDou-2 and the European Galileo.
The Xsens onboard sensor fusion algorithm combines all these measurements, ensuring the best performance and the least amount of drift with and without external reference. Through combining GNSS, INS and AHRS techniques that enhance each other, Xsens is able to provide powerful navigation solutions.
The MTi-7 is a miniature, low power and extremely lightweight GNSS/INS and AHRS that makes use of an existing GNSS infrastructure. It accepts external GNSS receiver data and fuses it on-board with the accelerometer, gyroscope and magnetometer measurements in order to produce Roll, Pitch and absolute Heading estimates that are unprecedented at this form factor.
Its low cost and low-level communication through UART, SPI and I2C interfaces make the MTi-7 ideal for integration into high volume applications. The MTi-7 is available as part of a Development Kit that includes a GNSS receiver and micro USB connection for quick testing, prototyping and development. Example codes for various embedded platforms and languages provide the user with a head start in developing their own software for configuring, communicating and processing. A no-EOL policy ensures that future versions of the MTi-7 will be drop-in replaceable.

The MTi-G-710 is an industrial grade IMU-enhanced GNSS/INS and AHRS that provides high-quality position, velocity, acceleration and orientation at high output rates, even in challenging environments. The optimized temperature calibration of the internal sensors combined with twenty years of experience in sensor fusion delivers reliable data for high demanding industrial applications. The module makes use of vibration rejecting gyroscopes and accelerometers and comes in a robust encased design that is IP67 rated and tested for vibration resistance.
The MTi-G-710 is ideal for plug-and-play use as it is easy to integrate into any application. The large range of communication interfaces, powering options, output modes and synchronization options allow for direct integration into a large range of applications, from maritime to aerospace and from autonomous driving to outdoor mapping. By using our interactive graphical user interface for Windows and Linux, first measurements are obtained in a matter of minutes.
