Large vessels require reliable heading instruments, and gyrocompasses meet that need perfectly. Due to their size and mass, large ships demand a system that delivers consistent heading information unaffected by environmental magnetic variations. A gyrocompass not only ensures accurate navigation but also feeds vital data to autopilot systems, radar overlays, and ECDIS. Without it, managing course, collision avoidance, and regulatory compliance would be severely compromised, putting the vessel and crew at risk.
