1 What is AIS?
AIS is the short form for Automatic Identification System Since 01.01.2005 all
SOLAS-Ships above 300 tons and all passenger vessels have to be equipped with AIS.
All ships equipped with AIS permanentl broadcast via two dedicated VHF channels (CH
87B and 88B) information about their MMSI-number (MMSI: The vessel’s Maritime
Mobile Service Identit number), call sign, name, position, course, heading, speed, rate
of turn and t pe of vessel. AIS enables all participants (ships and VTS stations) to
receive information about traffic in their vicinit and to use these data for their own
purpose, especiall for collision avoidance. So small boats such as achts no longer
have to guess whether a high speed ferr that just appears over the horizon could
cause danger to them - AIS automaticall calculates the CPA (Closest Point of Approach)
and TCPA (Time to Closest Point of Approach). As vessel information such as the name
and call-sign are known, when in doubt, ou can simpl give a call via VHF or even
make a DSC-call to the other vessel. In particular, AIS S stem is of great interests for
pleasure boats. Initiall , displa ing AIS data was onl possible with expensive
vector-chart-s stems. Nowada s the acht-AIS software enables ou to displa AIS
data on our PC in conformit with IMO and IALA recommendations. All ou need is (1)
the Yacht-AIS software and (2) a unit of AIS receiver or transponder.
San Jose Technolog Inc. (Sanav) offers reliable AIS s stems, including: (1) AIS
receiver; and (2) AIS transponder. Please contact Sanav’s sales or technical team for
further information.

2.3 LED Indicators
(Front side: from left to right)
ON
This is a green LED which indicates, when lit, that the power has been connected
correctl to the transponder and the power switch has been turned on.
Status
This is a green LED which indicates, when lit, that the transponder hardware has been
configured well. (The setup is correct: the operating software is present and running;
and the CPU has activated).
Timeout
This is a ellow LED which indicates, when lit, the transmitter is prevented from
transmitting.
If the unit has not transmitted a position report during the last two reporting intervals
(nominal reporting interval can not be maintained for operational reason, e.g. message
23 quiet period, high VDL load).
The reasons ma be that the transponder is unable to transmit an AIS message due to
the channel being alread occupied; for instance, b transmissions from other AIS
transponders.
Error
This is a red LED which indicates, when lit, that one of the following status conditions is
possible:
1. Transmitter lockout timer (1 second maximum) has operated.
2. GPS is not able to fix the position after 30 minutes.
3. Power Supply is out of range.
4. Background noise level is above the threshold level (-77dBm).
5. When the system initiation of the AIS-700 fails.
TX Off
This is a blue LED which indicates, when lit, that the remote TX Off switch has been
operated to manuall stop the AIS-700 from transmitting data.
RX
This is a green LED which indicates, when flashed, that the AIS-700 is receiving data
from other AIS transponders and is outputting this data as VDM NMEA sentences on the
output data ports.
If the green LED that constantl lit without flashing, it indicates that the unit has not
been programmed with its personalized data. It will still send received data to the
output port, but will not transmit an data.
TX
This is a red LED which indicates, when flashed once, that the AIS-700 is transmitting
its own AIS data.

4 Installing an AIS VHF Antenna
The VHF antenna is not included in the AIS-700 package because the installation of
antenna is different from one vessel to another. You can find an antenna from a marine
electronics outlet.
The AIS VHF antenna should be placed in an elevated position that is as free as possible
with minimum of 0.5 meters in the horizontal direction from constructions made of
conductive materials. The antenna should not be installed close to an large vertical
obstruction. The objective for the AIS VHF antenna is to see the horizon freel through
360 degrees.
The AIS VHF antenna should be mounted directl above or below the ship’s primar
VHF radiotelephone antenna, with no horizontal separation and with a minimum of 2.8
meters vertical separation. If it is located on the same plane as other antennas, the
distance apart should be at least 10 meters.

Here are some suggestions before ou bu an antenna and installation.
1. Antenna T pe: VHF antenna
2. Connector t pe: BNC plug, 50 ohms.
3. Separate the AIS VHF antenna as far as possible from the other VHF antenna.
4. The AIS VHF antenna should be at least 3 meters awa from the high power
transmitters.
5. The antenna should be able to see the clear sk and avoid the large obstructions.
6. The higher the antenna is mounted, the longer the range is.
