Aids to Navigation

Aids to navigation, such as lighthouses, beacons, navigational and mooring buoys and DGPS.

The Hydrographic Department of the Maritime and Port Authority of Singapore (MPA) manages the operation and maintenance of five lighthouses and a few hundred beacons, navigational buoys and mooring buoys. It also operates a Differential Global Positioning System (DGPS) broadcast service.

We use an integrated computer-based monitoring system to ensure that the lights of the lighthouses are functioning. The system alerts our shore-based authorities when these lights are faulty or not functioning.
