Stellar-40 is a tactical-grade inertial navigation system from SBG Systems, powered by the SAF2Nav engine for resilient navigation across land, airborne, and marine environments. It combines a 0.6°/h-class tactical-grade IMU, a jamming- and spoofing-resilient GNSS receiver, built-in magnetometers, and multi-sensor fusion within a rugged mechanical design. Designed for scalability, the system supports autonomous navigation in GNSS-denied environments and incorporates automatic anti-jamming and anti-spoofing detection.
The hardware incorporates IMU-level damping, a rugged enclosure, and embedded vibration spectral analysis. For Land/Air applications, a damped configuration adds external isolation and is recommended for high-vibration environments. Stellar-40 outputs IMU and INS data at 200 Hz and provides Ethernet, serial RS232/RS422, CAN 2.0 A/B, and synchronization I/O, alongside NMEA, binary sbgECom, REST API, and third-party protocols. PX4, ArduPilot, and ROS 2 drivers are supported. The SAF2Nav framework can accept air data, odometer, generic position, and generic velocity inputs in Land/Air configurations, while the Marine configuration supports DVL, Loch, USBL, depth sensor, and generic velocity aiding.
