  • Page 11: General

    The RA-2500 is a ship borne AIS Receiver (Automatic Identification System) capable of receiving navigation data and ship data from other ships and costal stations. The RA-2500 system consists of a receiver, a cable and connector to PC (RS-232), a AC adaptor and a combined VHF/GPS antenna.

  • Page 13: System Overview

    1.3 System overview The system is based on the IMO regulation for Universal AIS. The system is synchronized with GPS time to avoid conflict among multiple users. The VHF channels 87B and 88B are commonly used in addition to local AIS frequencies. The AIS receiver receives various data as specified by IMO and ITU on the frequency manually set up by the user.

  • Page 17: Using Ethernet Interface

    Using Ethernet interface Using this port, the RA-2500 is connected to the Ethernet port on a PC or a network node. See chapter 7.3 for description of LAN connector. Not all ships carry AIS It is important to remember that not all ships carry AIS, in particular leisure crafts, fishing boats, warships and some costal shore stations including Vessel Traffic Service Centers.

  • Page 19: Installation

    Install the VHF whip antenna referring to figure 4.1.3. Separate this antenna from other VHF radiotelephone antennas to prevent interference to the RA-2500. To minimise interference effects, the following guidelines apply: 1. The AIS VHF antenna should be placed in an elevated position that is as free as possible with a minimum of 0.5 meters in the horizontal direction from constructions made of...

  • Page 20: Gps/Vhf Combined Antenna

    3. There should not be more than one antenna on the same plane. The AIS VHF antenna should be mounted directly above or below the ship's primary VHF radiotelephone antenna, with no horizontal separation and with a minimum of 2.8 meters vertical separation.

  • Page 22: Cable Installation

    For optimum performance of the transponder approximately +10dB gain should be available when the cable attenuation has been subtracted from the GPS antenna preamplifier gain. Note that Procom AIS2/GPS and Comrod AC17-AIS are combined VHF/GPS antennas and additional attenuation from connectors/ diplexer must be taken in consideration. Some examples below: Cable Type Antenna Preamplifier Gain...
