OxTS Announces New xOEMcore Inertial Measurement Unit

Published: 05 Feb 2015

Oxford Technical Solutions xOEMcore IMUOxford Technical Solutions, a supplier of MEMS-based inertial navigation systems, has announced its newest OEM product. The xOEMcore, the company’s first standalone IMU, contains 6-axis gyros and accelerometers on a miniature OEM board set.

The xOEMcore is small, light and low-power. The inertial sensors have low drift rates, and less than 5m drift after 60s can be achieved in real-time with only odometer aiding. Heading, roll and pitch can be accurate to 0.05°, far exceeding magnetic heading and vertical reference system performance.

The small IMU block also houses an on-board processor running the Kalman filter, allowing users to get raw IMU measurements like a standard IMU, and can also be paired with an external aiding device such as a GNSS receiver with the xOEMcore taking care of the sensor fusion.

With the xOEMcore, system integrators get access to the high-grade MEMS IMU with the additional option of taking advantage of OxTS’s advanced sensor fusion and GNSS processing. gx/ix™ technology is available with the xOEMcore providing a tightly coupled solution with inertially-aided RTK relock for robust performance in even the harshest GNSS environments.

Whether using GNSS, LiDAR, WiFi, or other aiding devices, the xOEMcore seamlessly fuses the measurements with the inertial data. This combines the reliability and stability of inertial systems to ensure users get a continuous, robust solution at 100 Hz with minimal latency.

The xOEMcore provides continuity from one point to the next, so detecting unexpected measurements from other devices is easy. With deterministic error growth, the user will always have a good idea about what accuracy is being achieved, and the high update rate and low, fixed delay make controlling vehicles and robots much easier.
