The IQNS is a complete GNCC system, evolving from the proven GS4 INS with an upgraded NVIDIA-based edge processor. Incorporating NVIDIA Orin NX hardware, a single-axis FOG for heading stability, and an advanced AHRS with integrated pressure sensing, the unit delivers precise real-world navigation for defense and EOD operations. Built on Greensea’s OPENSEA software environment, IQNS combines navigation, vehicle control, and perception in a format tailored for integration into small subsea vehicles.
The system provides local navigation, command, and control directly on the vehicle, enabling stable operation over low-bandwidth or degraded communications links. Supporting ATR, obstacle avoidance, target tracking, and scalable AI/ML workloads, it reduces operator burden and enhances autonomy in demanding underwater missions. The system also integrates seamlessly with Greensea’s EOD Workspace and EOD Edge platforms, allowing defense users to implement contingency behaviors, expand payload capabilities, and advance autonomy without requiring additional topside infrastructure.
