Global Maritime Distress and Safety System (GMDSS)

GMDSS is a safety of life system that helps keep mariners safe in emergency situations while at sea. Utilising satellite and terrestrial technology, on-board systems are designed to prevent accidents, quickly alert rescue authorities and nearby vessels in the event of an emergency. 

Under the Safety of Life at Sea (SOLAS) convention, cargo ships of 300 gross tonnes and upwards and all passenger ships on international voyages must be equipped with satellite and radio equipment that conforms to international standards. GMDSS systems are equally valuable and increasingly prevalent on “voluntary fit” vessels such as recreational boats and leisure yachts.

AST provides dependable solutions for the maritime industry that enables global connectivity for mariners anywhere in the world. From terrestrial radios, GSM handsets to complete GMDSS compliant solutions, AST has the safety of your vessel and crew welfare covered if disaster strikes, and when communication is critical.
