Marine Automatic Identification Systems (AIS)
AIS (Automatic Identification System) enables vessels to share navigational data—such as position, speed, course, and identity—with nearby ships and shore stations. It enhances maritime situational awareness, collision avoidance, and traffic management across all vessel classes.
AIS units come in three types: Class A (required on commercial ships), Class B (for recreational and smaller craft), and Receive‑Only receivers. PSI carries reliable AIS solutions from leading brands to meet compliance and performance needs.
History and Innovation
AIS was standardized in the early 2000s under IMO and ITU regulations to enhance maritime safety. Initial transponder systems only broadcast basic data. Modern AIS devices now feature integrated GPS timing, collision‑avoidance alarms, and automatic self‑reporting mechanisms.
Recent innovations include AIS data overlay on radar and chartplotter screens, built‑in DSC VHF capability, satellite AIS reception, and Wi‑Fi-enabled AIS receivers that stream real‑time vessel information to mobile apps. Dual‑channel and multi‑constellation GPS support ensure enhanced accuracy and redundancy.
