Ellipse2-A
Motion & Heave
Ellipse2-A is a small-sized high performance Motion Reference Unit (MRU). It provides Roll, Pitch, Heading, and Heave data that adjust automatically to the sea state.
Ellipse2-N
Motion, Heave & Navigation
Ellipse2-N is a miniature inertial navigation system. For such a compact and cost-effective sensor, the features an advanced heave capability which delivers a 5-cm heave which automatically adjusts to the wave period.
Ellipse 2 Micro AHRS
Volume Application
Ellipse 2 Micro AHRS runs an Extended Kalman Filter to provide Roll, Pitch, Heading, and Heave. It is the only Micro sensor to provide a 5 cm Heave, automatically adjusted to the wave period
Case studies
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
MTR Article on Bathymetric USV
The Perfect INS for USV-based Bathymetry Like most unmanned systems, USVs have space and power constraints. Ekinox-D is the best INS to be integrated into this type of vehicle. Weighing less than 600 grams and low power (<7W), the Ekinox-D INS integrates an RTK dual antenna GNSS receiver for a centimeter-level position. It provides a … Continued
Ports of Jersey Choose the Apogee-U
Multibeam System for Ports of Jersey Ports of Jersey, UK, took delivery of a new Multibeam system from Swathe Services last week. The equipment, software and support package was chosen by Aaron Gavey, deputy Marine Operations manager, to enhance the organisation’s new commercial survey capability. (…) Aaron and his team chose: the new SBG Systems … Continued
Tips
The Right Option for Heave Data
When selecting your SBG sensor, note that the Gyroscopes and Accelerometer option should be G4A2.
Waterproof but not Salt Waterproofed
SBG miniature sensors enclosures are rated IP68, it means they are resistant to dust and water. If the sensor will encounter salt water, we recommend to build your own protection.
Magnetometer-based Heading Calibration
The SBG iron calibration tool compensates soft and hard iron effects using a powerful calibration algorithm. We recommend to perform the calibration in real conditions to obtain the best performance.
