Applied Research, Volume 5, Issue 5, October 2026.A digitalised Aids‐to‐Navigation monitoring system (ARMS) was deployed across 478 installations in the Strait of Malacca and Malaysian waters, integrating multi‐sensor edge validation, hybrid AIS/VHF/cellular communication, and a centralised platform. It achieved 98.3% availability and cut fault‐detection time from weeks to just 8.4 min.
