AIS Aid to Navigation (AtoN) – Type3 User Guide V1 English Weatherdock AG www.easyAIS.
1 References • General Warning All marine automatic identification system (AIS) units utilize a satellite based system such as the global positioning satellite (GPS) network or the global navigation satellite system (GLONASS) network to determine position. The accuracy of these networks is variable and is affected by factors such as the antenna positioning, how many satellites are used to determine a position and how long satellite information has been received for.
There are no known restrictions for the usage of the easyTRX3 in EU countries. Weatherdock AG www.easyAIS.

5 Introduction 5.1 General Information about 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.
• Class B transceivers Similar to Class A transceivers in many ways, but are normally lower cost due to the less stringent performance 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.
5.4 Type 3 AIS AtoN A Type 3 AIS AtoN has transmit and receive capability and can therefore use either the FATDMA or RATDMA (Random Access Time Division Multiple Access) access schemes. The RATDMA scheme allows the AIS AtoN to internally allocate slots for transmission of AIS messages without reservation from an AIS Base Station. Optionally the AIS receive capability also allows a Type 3 AIS AtoN to be configured and queried for status via AIS messages sent from a shore station (known as VDL configuration).
Figure 3 - AtoN supported messages Reporting intervals are: Msg. 21 (AtoN): 3 minutes (autonomous mode = default) Msg. 6, 8, 21 (AtoN): 10 seconds up to 1 day (assigned mode = special configuration) The easyAtoN is able to incorporate virtual AtoN (i.e. transmitter location is different from the AtoN position). Up to eight1 virtual AtoN can be realized with one easyAtoN.
6 Installation 6.1 Mounting Figure 4 - easyAtoN - connectors and plugs The VHF antenna should be mounted on a high position of the structure (e.g. buoy). It should not be mounted in parallel or in front of metal parts; these would lower the radiated VHF signal power and reduce the range of the AtoN. Weatherdock AG www.easyAIS.
6.2 Drilling Mask Figure 5 - easyAtoN drilling mask Weatherdock AG www.easyAIS.
When mounting the easyAtoN, pay attention to the mounting direction because of the internal GNSS antenna. In case of using an external GPS antenna connected to the easyAtoN, you are free in mounting. Wall mounting: ✓ ✓ ✓ X Flat mounting: Mounting the easyAtoN on top of a horizontal surface, as lying on a table, is also possible. 6.3 VHF Antenna Any VHF marine band antenna covering the marine band (156.025 .. 162.

Figure 8 - programming software 7.3 ‘Real’ AtoN configuration By default you need to configure the real AtoN at first. This is the physically existing transponder. In the table at the bottom of the form two schedules are implemented. The first with the Index 0 is the “on-position” reporting and schedule index 1 is used, when the AtoN is “off-position”, which means it is drifting and has moved outside the “Of Position Threshold”.
