Inertial Measurement Unit (IMU)

An Inertial Measurement Unit (IMU) is a self-contained system that provides raw, calibrated sensor data regarding linear and angular motion. The unit usually does this with a triad of gyroscopes and a triad of accelerometers. An IMU can either be gimballed or strapdown, outputting the integrated quantities of angular velocity and acceleration in the sensor/body frame. The sensors are commonly referred to in literature as rate-integrating gyroscopes and accelerometers. IMUs are often used as building blocks in more complex systems.

IMU quality levels range considerably. At Xsens, we hold the tension between pricing and performance, offering high quality and industrial robustness along with easy configurability, broad synchronization options, and excellent end-of-life management.

Vertical Reference Unit (VRU)

A vertical reference unit (VRU) measures roll, pitch, and (unreferenced) yaw. Its sensor-fused data – which can include the heading and other kinds of data, depending on the application and required performance level – is used for dynamic positioning in a variety of contexts. VRUs are the perfect solution for locations with high magnetic interference, as they do not rely on magnetic referencing.

Attitude and Heading Reference System (AHRS)

An Attitude and Heading Reference System, or AHRS, provides 3D orientation by integrating gyroscopes and fusing this data with accelerometer and magnetometer data. The yaw output is referenced to True North: with sensor fusion, drift that arises from the integration of gyroscope data is compensated for by reference vectors, namely gravity, and the earth’s magnetic field. This results in a drift-free orientation.

Its magnetic referencing ability distinguishes an AHRS from a VRU. It makes an AHRS a more cost-effective solution than conventional high-grade IMUs (Inertial Measurement Units), which only integrate gyroscopes, and rely on a very high bias stability of the gyroscopes. Along with our VRUs, our AHRS solutions are among the most highly demanded ISM solutions. An additional reason for this is the versatility of AHRS solutions: an high-performing Xsens AHRS can easily be retrofitted as a VRU or IMU.

Global Navigation Satellite System/Inertial Navigation (GNSS/INS)

If you are looking for an AHRS system that can combine internal orientation estimates with external positioning data from a receiver, you will be interested in our Global Navigation Satellite/Inertial Navigation Systems (GNSS/INS). A regular INS uses angular velocity and acceleration data from an IMU to compute a relative position over time. This means it will drift from its true position if no external reference is provided. A GNSS can provide this reference.

The combination of mutually enhancing GNSS, INS and AHRS techniques enables us to provide you with powerful navigation solutions offering the best performance and the least amount of drift – even when GNSS position updates are temporarily unavailable, for example, in tunnels or under bridges.

GNSS/INS solutions are quickly gaining ground in many application areas. These include UAVs requiring positioning data, automotive testing, autonomous vehicles and (port)trucks, marine, sea surface and port applications.

Real-Time Kinematic positioning (RTK GNSS/INS)

Real-Time Kinematic (RTK) positioning is a satellite navigation technology used to increase the precision of position data obtained from satellite positioning systems. Traditional GNSS receivers measure how long it takes for a signal to travel from satellites to the receiver. Using four or more satellite signals and positioning based on at least three known points (trilateration) will enable the receiver to calculate its position. These signals, however, can get distorted when passing through the ionosphere and atmosphere, affecting the calculated position accuracy (2 to 10 meters). RTK solves this issue by using real-time corrections from a base station. The base station knows its fixed position and therefore is able to estimate the errors of the received signals. This correction signal is then transmitted from the base station to the RTK receiver.

Marine and Ports

Maritime and port applications have to deal with many different factors, including highly changeable water and air motion. Reliability and precision are of the utmost importance in this field. Think for example, of underwater robotics, autonomous boats, maintaining the static stability of a ship on moving water, stabilized platforms for cameras or antennas, measuring sea or underwater motion, mapping the seafloor in hyperspectral detail, or maritime and port surveillance systems. The robust hard- and software, along with the anti-magnetic distortion filters of Xsens' MTi series, makes them a highly suitable, stable platform for motion technology applications at sea and in seaports.

What are Inertial Sensors?

An inertial sensor, or Inertial Measurement Unit (IMU), is an electronic device that monitors the specific 3D acceleration, angular rate or 3D rate of turn, and magnetic field of a (moving) object. It uses an accelerometer, a gyroscope, and a magnetometer to provide calibrated measurements on the motion of the object carrying it, such as a drone or autonomous vehicle. IMU technology is widely used in drones, robotics, fleet operations, digital mapping, test driving and flying, and warehousing, among other areas. For applications such as surveying, where the data have to be available after the operation, the IMU may be connected to an internal data logger.

Read more about our IMUs

At a more advanced level, sensor fusion technology is added in order to make orientation calculations on the basis of the data provided by the IMU. Depending on the technology used, either the roll, pitch and unreferenced yaw can be determined, or the roll, pitch and referenced yaw. In the first instance, the yaw output is relative to the zero point, that is, the yaw orientation when the filter was initialized or when the last heading reset command was sent. In the second, more advanced, instance, the yaw output is referenced to True North.

Read more about our VRU and AHRS systems.

At its most advanced level, motion tracking combines motion data and roll, pitch and yaw calculations with 3D positioning, 3D velocity and Global Navigation Satellite System/Inertial Navigation System (GNSS/INS) data. This means merging large datasets from different sources for richer and more precise outcomes. In high-precision applications, such as cadastral surveying or precision agriculture, sensor fusion is combined with Real-Time Kinematic (RTK) positioning. This satellite navigation technology can increase the precision of satellite positioning data down to centimetre-level.
