Designed for land, air, and marine platforms, Stellar-40 integrates a tactical-grade IMU, a GNSS receiver, and advanced sensor fusion algorithms within a compact and rugged enclosure. The system is developed to provide reliable navigation performance in high-vibration, high-dynamics, and electronically challenging environments. The development of Stellar-40 focused on two main objectives: increasing resilience in harsh operational conditions and improving production scalability. To overcome the vibration sensitivity commonly encountered in defense and industrial applications, SBG Systems implemented an innovative three-level mitigation approach: - **Sensor-level isolation: **dampers integrated directly at the IMU sensor level reduce vibrations at the source. - **Resonance-free enclosure:** a specialized housing engineered to drastically minimize resonance and internally induced vibrations. - **Structural isolation:** custom external dampers designed to isolate the unit from harsh vehicle dynamics.…
