  • Page 8: What Is Ais

    1 WHAT IS AIS? The Automatic Identification System (AIS) is a Very High Frequency (VHF) radio broadcasting system that transfers packets of data over the VHF data link (VDL) and enables AIS equipped vessels and shore-based stations to exchange identification information and navigational data.

  • Page 9: System Overview

    SOLAS vessels, commercial ships, professional vessels, and non- SOLAS applications. The A750 can be connected to the ship’s sensors as required by the IALA guidelines through junction box. The device can also interface external navigation and presentation systems that support IEC 61162-1 related sentences. It is also capable for connection to Long Range system like Inmarsat C.

  • Page 13: Vhf Antenna Installation

    VHF Antenna Installation The quality and positioning of the antenna are the most important factors dictating AIS performance. It is recommended that a VHF antenna with omni directional vertical polarization be specifically tuned for AIS operation band. Since the range of VHF signals is largely decided by line of sight distance, the VHF antenna should be placed as high as possible and at least 5 meters away from any constructions made of conductive materials.
