Ekinox-A

Motion & Heave AHRS/MRU

Ekinox-A 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.

Typical application

Ekinox-A can be used as AHRS, Vertical Gyro, MRU, IMU for Ship Motion Monitoring, Buoy & ROV orientation, and embedded imagery system orientation and stabilization such as Sonar, LiDAR, Camera, Antenna, etc.

Distinguishable features

Ekinox-A delivers real-time auto adjusting heave on 4 monitoring points, handles magnetic disturbances, and provides NMEA outputs. This motion sensor computes an enhanced heave based on position and speed computation, and robust heading even during turns thanks to Single or Dual Antenna GPS inputs. With a low latency (<3 ms), a high output rate (200Hz), and a very low noise on Euler Angles (<0.03°), the Ekinox-A is a cost-effective alternative solution for mobile equipment orientation & stabilization.
