Bevegelsessensor (MRU) med forbedret kompass og GNSS-basert bevegelsesestimering

Offentlig prosjektsammendrag

The project will develop a new Motion Reference Unit (MRU) with significantly improved heading, roll and pitch accuracy under realistic vessel conditions. Today, compact MRUs are limited by calibration constraints, magnetic disturbances and dynamic motion, while high-performance FOG systems are too expensive, large and power consuming. The project will address four main challenges: developing calibration methods that work with restricted vessel motion, improving heading estimation during roll and pitch, suppressing magnetic disturbances, and integrating GNSS velocity to improve roll and pitch accuracy during dynamic maneuvers. The work will be carried out systematically through algorithm development, simulation, laboratory testing and sea trials with customers. The outcome will be a compact and cost-efficient MRU that delivers performance close to FOG systems, enabling many new applications where existing MRUs are insufficient and FOG systems are impractical.
