SBG Ekinox-A: Attitude and Heading Reference System

Ekinox-A from SBG Systems is an advanced Attitude & Heading Reference System (AHRS) or MRU (Motion Reference Unit). It combines high end gyroscopes and accelerometers, and runs an enhanced Extended Kalman Filter (EKF) to provide Roll, Pitch, Heave, and Heading when connected to an external GNSS receiver.



The Ekinox-A AHRS from SBG Systems uses high end MEMS combined with powerful algorithm design and advanced calibration procedures to deliver a robust product that is both cost-effective and maintenance free. This makes the product a powerful solution for many applications including buoys, ship motion monitoring, sonar, ROV, camera motion compensation and LiDAR. Heading and enhanced heave is calculated based on speed and position computations, even during turns by using Dual Antenna GPS inputs.

The Ekinox-A has low latency, high output rate and a very low noise on Euler Angles, making it an excellent alternative to FOG technology for mobile land equipment stabilization and orientation. Typical land applications include gyro stabilized camera and targeting systems.

Rated to IP68 and being temperature calibrated from -40 °C to 75 °C, this AHRS can easily withstand harsh environments, and will deliver precision even in high vibrating conditions.
