Icom proudly announces the debut of a new cat-
egory product, the AIS (Automatic Identification
System) receiver, MXA-5000. The MXA-5000 is
developed as one component of a new net-
worked marine navigation system*, however, by
connecting it to third party navigation equip-
ment or a PC, the MXA-5000 offers AIS data for
monitoring other vessels traffic. It provides use-
ful information for collision avoidance even
where the marine radar may fall off the screen
such as the blind side of an island or winding
shore line.
* Released later.
What is AIS?
The AIS (Automatic Identification System) provides in
real-time a vessel’s navigation information to the vessel
traffic center or other nearby ships by using digital data
over VHF channels. SOLAS vessels are obligated to
install an AIS transponder under SOLAS regulations.
The AIS transponder sends accurate navigation informa-
tion such as:
• Static Information — Vessel call sign, name, MMSI
number, dimensions, type
• Voyage-Related Information — Draft, cargo type, desti-
nation and estimated time of arrival
• Dynamic Information — Time in universal time, coordi-
nated, latitude/longitude position, course over ground,
speed over ground, heading, rate of turn, navigational
status.

Dual channel receive capability
The MXA-5000 receives both Ch. 87B (161.975MHz) and Ch. 88B (162.025MHz) simultaneously and
improves accuracy of data received. This dual channel receive makes the MXA-5000 more flexi-
ble for obtaining AIS information from transmitters that operate on only one of the AIS channels.
Third party navigation equipment connection
The MXA-5000 has an IEC 61162-1 standard (38,400 bps) interface using a RS-422 balanced con-
nection for third party navigation equipment. Navigation equipment such as marine radar or GPS
chartplotter which accept the VDM sentence format will show the AIS data on the display.
PC connection
The MXA-5000 also has an RS-232C unbalanced connection for PC connection. When using with
an AIS plotter software*, the MXA-5000 allows you to monitor the vessel’s traffic from land for pro-
fessional or hobby use.
* For example, ShipPlotter is available with MXA-5000. “http://www.coaa.co.uk/shipplotter.htm”
GPS input
When installing the MXA-5000 to a vessel, the MXA-5000 can be connected between GPS receiv-
er and navigation equipment for data input and output. The GPS position information such as
RMC, GGA, GNS and GLL formats can be multiplexed with AIS data (VDM format).
Sharing single VHF antenna with VHF radio
The MXA-5000 has two antenna connectors for installing the MXA-5000 between a VHF antenna
and a VHF radio. The MXA-5000 eliminates the need of a new VHF antenna for AIS reception.
When you transmit from the connected VHF radio, TX signal bypasses the MXA-5000 protecting
the internal circuit of the MXA-5000.
Compact size and light weight body
The MXA-5000 has only 132(W)×34(H)×155(D) mm dimensions and weighs only 400g for easy
and flexible installation.
