Navigation
Maintenance-free solutions providing highly accurate input to autopilot systems on any type of ship or high-speed craft, replacing conventional gyrocompasses and increasing navigational performance and safety while reducing wear and tear on steering gear.
Maintenance-free navigation with MGC®
The Motion Gyro Compass (MGC®) from KONGSBERG is a maintenance-free, IMO type-approved gyrocompass designed for reliable navigation across all vessel types.
Using three Motion Reference Units (MRUs) and three ring laser gyros (RLGs), the MGC calculates heading internally from roll, pitch and heave. This allows vessels to compensate for their own movement, even in rough seas or changing orientations, without relying on external signals. The result is consistent, accurate heading data that supports safe and efficient navigation, especially in busy waterways or during complex manoeuvres.
Unlike magnetic compasses, which are vulnerable to interference and less reliable near the poles, the MGC offers robust north-seeking capability. It is a dependable choice for polar expedition vessels and increasingly relevant for merchant ships operating in the opening Northeast and Northwest passages.
Wide range of products
The MGC is available in five models, including the MGC R1 – a popular choice for bridge navigation systems. It integrates seamlessly with KONGSBERG systems, simplifying installation and reducing compatibility issues in retrofits.
With no moving parts, the MGC is compact, lightweight and energy-efficient. It meets Safety of Life at Sea (SOLAS) requirements for 10-year maintenance-free operation, with no recalibration needed.
