MTR100: SBG Systems

Marine Technology Reporter
SBG provides MEMS-based inertial motion sensing solutions. The company provides a wide range of inertial systems from miniature to high accuracy. Combined with cutting-edge calibration techniques and advanced embedded algorithms, SBG Systems products are geared for aerospace, land, and especially marine – surface and subsea – projects such as vessel motion monitoring, ROV and AUV control, hydrography and buoy positioning.
SBG Systems delivers high performance and cost-effective MEMS-based Motion Reference Unit (MRU) and Inertial Navigation Systems (INS) to the Marine industry, representing approximately half of the company’s turnover. Its products are mainly used in offshore, marine, and underwater applications, including hydrography, USV, AUV and ROV navigation and motion monitoring
SBG Systems designs, manufactures and calibrates all of its products. SBG Systems adds value to its inertial systems by designing specific data fusion algorithms and calibration techniques to enhance sensors’ performance. The company’s Apogee Series is the most accurate line of inertial navigation systems based on the robust and cost-effective MEMS technology. Apogee sensors are also the smallest and lightest at this level of accuracy. It provides a roll and pitch accurate to 0.008° in real-time and integrates the last generation MEMS sensors and tri-frequency GNSS receiver for centimeter-level position and GNSS-based heading, not sensitive to latitude. The INS also deliver a real-time heave accurate to 5 cm in real time and 2 cm with the delayed heave feature.
SBG Systems has developed advanced testing and calibration techniques for bias, gain, linearity, misalignments, cross-axis, gyro-g over. Every product is intensively tested, temperature calibrated, and shipped with its individual calibration report. The company owns a full calibration lab including shakers and rotary tables with environmental chambers.
