Nautilus Navigation in Space

Nautilus Navigation in Space is an Israeli aerospace startup developing autonomous navigation and guidance systems for satellites and space vehicles operating in environments where GPS signals are unavailable or unreliable. The company addresses a key challenge in modern space operations: how to navigate precisely beyond GPS coverage or in GPS-denied environments such as deep space, high Earth orbit, and lunar vicinity.

Nautilus technology uses a combination of star tracking, onboard processing, and innovative sensor fusion algorithms to deliver precise position and attitude determination for small satellites, orbital transfer vehicles, and lunar spacecraft. This enables mission-critical maneuvers — orbit transfers, rendezvous, proximity operations — to be performed autonomously without ground intervention.

Backed by Israeli space industry expertise and connected to Israel's vibrant space startup ecosystem, Nautilus targets commercial satellite operators, spacecraft manufacturers, and space agencies seeking to enhance spacecraft autonomy and reduce dependence on ground-based navigation support. The company is developing products suitable for CubeSats through mid-size commercial satellites.
