Only qualified personnel should work
inside the equipment.
Do not disassemble or modify the
equipment.
Fire,electrical shock or serious injury
can result.
Immediately turn off the power at
the switchboard if the equipment is
emitting smoke or fire.

Fire or electrical shock can result if the
power is left on.
Be sure that the power supply is compatible with the voltage rating of the equipment.
Connection of an incorrect power
supply can cause fire or equipment
damage.
Use the proper fuse.
Use of a wrong fuse can damage the
equipment or cause fire.

How AIS Works
1. What is AIS
AIS stands for Automatic Identification System. AIS increases navigational safety and collision avoidance by transmitting vessel identification, helping to reduce the difficulty of identifying ships when not in sight (e.g. at night, in radar blind arcs or shadows or at distance) by broadcasting navigational intentions to other vessels by providing ID, position, course, speed and other ship data with all other nearby ships and land based stations.
According to IALA regulations, AIS is defined as follows:
AIS is a broadcast Transponder system, operating in the VHF maritime mobile band. It is capable of sending ship information such as identification, position course, speed and more, to other ships and to shore. It can handle multiple reports at rapid update rates and uses Carrier Sense Time Division Multiple Access (CSTDMA) technology to meet these high broadcast rates and ensure reliable and robust ship to ship operation.
The IMO defines the performance standards as follows:
Ship to ship working, ship to shore working, including long range application, automatic and continuous operation, provision of information messaging via PC and utilization of maritime VHF channels.
2. What AIS classes do exist?
There are two classes of AIS units fitted to vessels, Class A and Class B. In addition AIS base stations may be employed by the Coastguard, port authorities and other authorized bodies. AIS units acting as Aids to Navigation (A to N) can also be fitted to fixed and floating navigation markers such as channel markers and buoys.

2.1 Class A
Class A units are a mandatory fit under the safety of life at sea (SOLAS) convention to vessels above 300 gross tons or which carry more than 11 passengers in International waters. Many other commercial vessels and some leisure craft also may be fitted Class A units.
The Class A operation consists of three different types of messages:
Dynamic information:
position of the ship (derived from GPS)
time, when the position was measured in UTC course over ground (COG)
speed over ground (SOG) heading (HOG)
ship status
rotational speed/turn rate
Static information:
MMSI number
call sign and name of the vessel length and width of the vessel
IMO-number of the vessel, if existent type of vehicle
position of the GPS sensor onboard
Journey-related information: draught of the vessel type of cargo
port of destination and estimated time of arrival (ETA)
route plan, optional compulsory way, depending on the vessels movement.

The following table shows the mandatory repetition rate of class A transmissions linked to the ship`s movement:
anchored vessels 3 minutes vessels at 0 
14 kn 10 seconds
vessels at 0 
14 kn, fast maneuver 3.3 seconds vessels at 14 
23 kn 6 seconds
vessels at 14 
23 kn, fast maneuver 2 seconds vessels at > 23kn 2 seconds
vessels at > 23 kn, fast maneuver 2 seconds
Static information as well as information belonging to the journey is dispersed every 6 minutes.
The reporting intervals correspond to both radio channels (161.975 MHz, 162.025 MHz) together.
2.2 Class B
Class B: EN62287, 2005:
class B operation is described in the standard EN62287, published in 2005. This document is obligatory for class B.
Class B units are designed for fitting in vessels which do not fall into the mandatory Class A fit category.
The KS-200A is a Class B AIS unit
Reporting intervals are:
Dynamic ship data:
boats at < 2 kn: 3 minutes boats at > 2 kn: 30 seconds
Static ship data (similar to class A): 6 minutes
These intervals are the standard operation modes. Competent authorities, like base stations, can have influence on the reporting intervals (as they do with class A as well). Interval timing can be reduced down to 5 seconds in exceptional cases. There is no automatism to change the 30sec/3min dynamic intervals by the ship itself.
