Test Conditions The SBG Inertial Navigation Systems have been tested during a three-day lasting hydrographic survey in the Hamburg (Germany) port area. SBG Systems and MacArtney Germany GmbH equipped a survey vessel with a complete Multibeam Echosounder survey configuration and conducted various tests to show the performance of the SBG Inertial Systems in different challenging … Continued
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
The SBG on-board hard and soft iron calibration tool allows for calibration in the water. It ensures a precise heading in any orientation by taking into account the real environment where the AUV will be gliding.
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.
