Cube Squared
Cube Squared builds navigation, sensing, and autonomy software for platforms operating where GNSS, communication links, and human operators are unavailable—underwater, in the air, and along critical infrastructure. Its physics-based acoustic and magnetic sensing, combined with GNSS-denied navigation, is field-validated in real sea conditions and over featureless terrain. The company serves Swedish defence agencies and major defence-industry primes.

Problem
Platforms operating in contested environments—underwater, in the air, and along critical infrastructure—often lose access to GNSS, communication links, and human oversight. Existing navigation and sensing solutions that depend on satellite positioning or continuous operator input fail in these conditions, leaving military and critical-infrastructure operators without reliable situational awareness or autonomous capability.
Solution
Cube Squared builds software and sensor systems that enable platforms to operate autonomously where external support is unavailable. The company combines physics-based acoustic and magnetic sensing with visual, inertial, and terrain-referenced navigation, applying real-time signal processing and source modelling to convert raw field measurements into actionable information. Its systems are designed for platforms that cannot rely on satellite positioning, which is inherently easy to deny. Every system is field-validated in its intended operating environment—underwater in the Stockholm archipelago and in the air over northern Sweden—rather than only in simulation. The same core mathematics—source modelling, sensor fusion, and decision-making under uncertainty—applies across both underwater and aerial use cases, allowing capabilities to scale from seabed to powerline operations.
Target Audience
Primary customers include Swedish defence agencies and major defence-industry primes developing underwater and aerial platforms for contested environments, as well as organizations responsible for protecting critical infrastructure.
