About AISPage 32 About AISThe marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped withAIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vesselidentity with similarly equipped vessels. Position is derived from the Global Positioning System (GPS) and communication betweenvessels is by Very High Frequency (VHF) digital transmissions. There are a number of types of AIS device as follows:•Class A transceivers. Are designed to be fitted to large vessels such as cargo ships and large passenger vessels. Class Atransceivers transmit at a higher VHF signal power than class B transceivers and therefore can be received by more distant vessels.They also transmit more frequently. Class A transceivers are mandatory on all vessels over 300 gross tonnes on internationalvoyages and certain types of passenger vessels under SOLAS regulations. •Class B transceivers. Similar to class A transceivers in many ways, but are normally lower cost due to the less stringentperformance requirements. Class B transceivers transmit at a lower power and at a lower reporting rate than class A transceivers. •AIS base stations. AIS base stations are used by Vessel Traffic Systems to monitor and control the transmissions of AIS transceivers. •Aids to Navigation (AtoN) transceivers. AtoN’s are transceivers mounted on buoys or other hazards to shipping which transmitdetails of their location to the surrounding vessels. •AIS receivers. AIS receivers will generally receive transmissions from class A transceivers, class B transceivers, AtoNs and AISbase stations but do not transmit any information about the vessel on which they are installed.•AIS AtoN Express. The AtoN Express is a unique, self-contained AIS Aid-to-Navigation. The key features of the AtoN Express areas follows:• Self-contained VHF and GPS antennas• Internal rechargeable battery pack for up to 5 days of operation• Simple installation
About AISPage 42.1 Static and dynamic vessel dataThere are two categories of information transmitted by an AIS device: static and dynamic data.The vessel's dynamic data, which includes location, speed over ground (SOG) and course over ground (COG), is calculatedautomatically using the internal GPS receiver. Dynamic data is not transmitted by AIS AtoN’s.Static data is information about the vessel or Aid-to-Navigation which must be programmed into the AIS device. This includes:• Maritime Mobile Service Identity (MMSI)• Vessel or AtoN name• Vessel call sign (if available, not relevant to AtoN’s)• Vessel or AtoN type• Vessel or AtoN dimensionsIn most countries the operation of an AIS AtoN device will require the local authority to grant an operating license and MMSI number.An MMSI number is required in order for the AIS device to operate. The product requires an AtoN specific MMSI number withthe format 99*******. Please contact the relevant authority in your country for more information. !

Installing and charging the AtoN ExpressPage 93.4 Charging the AtoN ExpressThe AtoN Express is shipped with a partial charge and requires a full charge prior to installation on a structure to be marked (unless theunit is powered via the Power box). The AtoN Express is charged by placing it in the configuration dock as shown in Figure 4.During charging the status indicator will flash blue at a steady rate (1 second on - 5 seconds off). When charging is complete the statusindicator will flash a shorter blue flash (100 milliseconds on - 5 seconds off). Depending on the condition of the battery a full charge cantake up to 5 hours to complete.Note that the AtoN Express can be configured as described in section 4 prior to charging.Figure 4 Charging the AtoN Express123 4123124578101196
Installing and charging the AtoN ExpressPage 103.5 Installing the Power boxAtoN Express is supplied with a Power Box which can be used to power the unit from an external 12 to 24VDC supply (absolute range9.6 to 32VDC). The Power Box is waterproof to IPx6 and IPx7.The Power box also charges the internal battery, so if the external power source fails the AtoN Express will continue working until theinternal battery is exhausted. The Power Box is supplied with a 6m cable and a connector which mates with the connector at the base of the AtoN Express. The inputpower cable is not supplied and will need to be fitted prior to installation.To fit a power supply cable:1) Remove the screws at each corner of the power box (see diagram 1).2) Loosen the cable gland on the pre-fitted cable.3) Remove the lid of the power box (feeding the attached cable through the gland).4) Feed the selected power supply cable through the unused gland. A 2 core flexible cable with an external diameter not exceeding6.5mm should be used.5) Connect the +ve conductor to the Red screw terminal and -ve conductor to the Black screw terminal (see diagram 2) 6) Carefully feed the cables back through their gland and refit the lid of the power box. Tighten the cable glands and refit the screwsat each corner of the lid (see diagram 3).7) The power supply can now be attached to the external power source (see diagram 4)When correctly connected to the external power source the Power Boxes green "Power" LED will be on.!The AtoN Express will not charge if the internal temperature is below 0°C or above 40°C. If the temperature is outsidethis range the status indicator will flash rapidly to indicate a charging fault.

This tab permits configuration of thefollowing information:•AtoN nameEnter the AtoN name or other identification.• MMSI numberEnter the AIS AtoN’s 9 digit MMSI number.• AtoN typeSelect the most appropriate AtoN type from the drop down list.• Type of EPFSThe EPFS used by the AtoN can be set to either Autonomous (uses the GNSS fix) or Surveyed (uses the nominal position entered). For surveyed positions the accuracy of the measurements (less than or greater than 10m) can be added.• Nominal PositionThe charted (or intended) location of the structure being marked.• Off Position Threshold.The distance (m) by which the AtoN my vary from its nominal position before it reports being off position.•RACON Fitted.Allows the setting of the racon fitted flag in the message #21 to indicated that a radar beacon is also available at the reported loca-tion.• Message ScheduleThe start slot, interval between messages and start UTC for both channels A and B can be configured for the message #21.• AtoN’s dimensionsEnter the AtoN dimensions, referenced to the location of the AtoN Express, to the nearest whole metre.• Configuration of AIS operating frequenciesSelect the required operating VHF frequencies for transmissions. The default channels are Channel A = 161.975MHz and Channel B = 162.025MHz. The default channels are intenationally reserved for AIS and should not normally be adjusted. For specific applica-tions the frequencies can be adjusted, but it is critical that they match the configuration of any receiving equipment.To copy the configuration to the AtoN Express click the send icon. Existing configurations can be retrieved from the AtoN Express usingthe retrieve icon.
Configuring the AtoN ExpressPage 14Figure 6 proAtoN Express configuration tab4.4 Message Schedule ConfigurationAtoN Express only transmits the standard AtoN message #21 using FATDMA. The scheduling of this message can be configured usingthe following parameters which can be can be entered independently for both channel A and B:FATDMA (Fixed Access Time Division Multiple Access) access scheme requires that the AIS AtoN is configured with fixed AIS timeslots in which it will transmit AIS messages. Mobile AIS stations operating in the area where an AIS AtoN is installed need to be awareof the time slots allocated to the AIS AtoN. The slots allocated to the AIS AtoN are 'reserved' by transmissions from an AIS Base Stationthat is operating in the same area as the AIS AtoN and is configured to make the necessary slot reservations. In some areas, wherethere is no base station coverage, local regulations may allow an AIS AtoN using FATDMA to be installed with out the slot reservationbeing made.
Configuring the AtoN ExpressPage 15•Start UTCThe offset from UTC 00:00. This parameter is used to create different start times for the two channels when alternating transmission between the two channels. For example; a five minute transmission schedule alternating between channel A and B would have a slot interval of 22500 (10 * 2250 slots per minute) and a difference of 5 minutes between the start UTC’s of the two channels.•Start SlotAs FATDMA is being used, the start slot should be reserved by the local base station. The start slot can be entered independently for both channels A and B.• Channel IntervalThis determines the time between transmissions on each channel. The interval is set as a number of slots. 2250 slots = 1 minute.The operating time from a complete charge is dependent on the configured reporting intervals. Shorter reportingintervals will reduce the operating time. The examples provided here are intended as a guide as actual operating timealso depends on external factors such as temperature and GPS signal quality.!
