Kongsberg Discovery is advancing GPS-free navigation by turning small, micro-electromechanical systems (MEMS) into north-seeking devices that detect Earth’s rotation.
Developed in collaboration with Silicon Sensing Systems, the device is based on a proprietary inertial measurement unit (IMU) and delivers high-precision navigation in a small, lightweight package.
Its solid-state design is optimized for mass production and cost efficiency, while providing tactical-grade accuracy and resilience against jamming and spoofing.
“In many ways, this opens up a whole range of new applications within navigation,” said Dalsnes Storsæter, vice president of Inertial Solutions at Kongsberg Discovery.
“From air and surface-based drones, to subsea [vehicles], to defense systems, marine surveying, energy applications, and beyond. The device allows for reliable, precise navigation without continuous aiding.”
Best of Both Worlds?
North-seeking sensors determine true north by aligning with the Earth’s rotation, enabling navigation even when GPS or magnetic compasses are unavailable.
Traditional north-seeking gyroscopes are often bulky, delicate, and expensive, limiting their use on compact platforms.
MEMS sensors, on the other hand, are small and affordable but typically less accurate and reliant on GPS.
Kongsberg’s innovation bridges that gap, pushing MEMS in north-seeking roles that rival other high-end navigation sensors.
Once deployed, the system could free up space on naval platforms for other equipment while maintaining precise directional guidance.
The company will showcase the tech at Oceanology International 2026, happening from March 10 to 12 in London.
