Smart Ships Need Smart Backup Navigation — Not a Return to the Past

he gap in our industry is clear. On one side, we talk about autonomous ships, AI support, and digital control. On the other side, some still say we should fall back on sextants and paper math when GPS drops. That approach does not match the ships we sail today.

A sextant is fine for training. It helps build basic skill. But it cannot guide a ship through tight tracks, busy seas, or bad weather. Modern risk needs modern backup systems.

We should move toward tools that match real work at sea. Electronic sextants can take sky fixes on their own. Vision systems can read the coast. Radar can match known points. LEO signals add strength when GPS is weak. Inertial units can hold a stable track for short gaps. Even UAVs can act as moving beacons when needed.

Most of all, we must think about people. Seafarers are human beings, not machines. They work under stress and need clear, smart support. They should be trained to use modern systems, not forced to rely on slow paper calculations.

Smart ships need smart layers of navigation. And smart training keeps people safe.
