Thanks to SBG System's team of specialists we have mastered our fields of expertise
SBG Systems is renowned for its expertise in sensor selection, extensive calibration techniques, and filtering. The aim is to take sensors to the best performance and reliability to offer competitive solutions to our customers.
SBG Systems has developed cutting edge data fusion algorithms, tailored for the inertial navigation needs. Depending on platforms, we operate either loosely or tightly coupled INS/GNSS extended Kalman filters (EKF) to enable the best performance in each application whether it is aerial, terrestrial, or marine.
We take a great care in refining our IMU and aiding equipment error models to ensure optimal performance is obtained with a wide range of equipment: IMU, GNSS, Dual antenna heading, magnetometer, odometer (DMI), DVL, and others. Our navigation filter also integrates your specific vehicle constrains, like automotive dynamic constraints, or marine enhanced altitude computation.
High precision is generally a key parameter, but high robustness can be even more important! That is why we designed advanced rejection filters and RAIM techniques, able to detect inconsistent measurement and exclude them from the user output. These algorithms ensure a robust positioning at all times.
The Ellipse series integrates a best in class magnetic calibration procedure. Able to cope with both “hard and soft Iron” effects and to operate even in both 2D and 3D applications, the procedure also aligns the magnetic and inertial coordinate frames to ensure optimal magnetic performance in most difficult environments. During the operation, our EKF is designed to greatly mitigate transient errors in the magnetic field.
SBG Systems has put strong efforts in designing high performance heave filters. Real time heave filter enable a quick data output without post-processing. For most demanding applications, it is possible to use a delayed heave algorithm, with zero phase errors, at the cost of a 150s delay.
Leveraging on our strong real time data fusion experience, SBG Systems has developed a forward/backward/merge post-processing solution called “Qinertia” to dramatically reduce errors in challenging environments.
