Wave Buoys in the Arctic Sea Ice
Marginal Ice Zone (MIZ) Program Over recent decades the Arctic has warmed more than any other region leading to significant reduction in sea ice volume. The combination of increased ice-free area and more mobile ice cover has led to the emergence of a seasonal marginal ice zone (MIZ) in the Beaufort Sea. The Office of … Continued

Tips
Magnetometer Calibration
The SBG on-board calibration tool allows calibration in water. It ensures a precise heading in all orientation by taking into account the real environment where the AUV will be gliding.
IMU, AHRS, or INS?
The Inertial Measurement Unit (IMU) outputs gyroscopes, accelerometers, and magnetometers raw data. The Attitude and Heading Reference System (AHRS) embeds an Extended Kalman Filter (EKF) to deliver orientation data, and the Inertial Navigation System (INS) additionally embeds a GNSS receiver for a filtered position in real-time.
