![]() ![]() M/v APL Detroit is outside of the AIS coverage areaĪs can be seen from the example below, the name of the vessel may be entered partially. If the vessel is found in the database, but at the moment is out of reach of AIS, you will see note Vessel is out of Range. m/v Eugen Maersk is within the AIS coverage area Click on the name in the list and you will see the vessel on the map. If the vessel is within reach of the AIS station, its name will appear in the drop-down list. Then start entering the name of the vessel in the upper field, where it is written Vessel, Port. ![]() Click on the icon with the magnifying glass icon to display the input form. To find a vessel on AIS map, you need to enter its name (or part of it) as shown in the pictures below. Also, some items may be displayed with a delay of up to one hour, which is not a big error if the ship is in the ocean (considering the small speed of the ships and the huge distances). However, the positions of some vessels may be updated with a delay, for example, when the vessel has exceeded the receiving range. In general, the data on the map is updated in real time. In some cases, ships can be seen on the map at a distance of 200 nautical miles (370 km!), if the antenna with the AIS receiver is located high enough (for example, on a mountain over 500 m). The reception quality also depends on the type of antenna, obstacles (mountains, buildings) and current weather conditions. The higher the AIS stations are, both shipboard and shore, the further the radio signal will spread. It is difficult to determine the maximum coverage area, but it can be imagined in this example: a vessel with an AIS transmitter connected to an external antenna located at a height of 15 meters above sea level will be able to exchange a signal with the coastal AIS station at a distance of 15-20 nautical miles (approximately 28-38 km).

Receiving stations cover the entire range of 40 nautical miles (about 75 km) and periodically receive information from some more remote vessels. r/HomeNetworking - Simpler networking advice.The system is based on Automatic Identification System (AIS). r/pfsense - for all things pfsense ('nix firewall) Might be able to find things useful for a lab. r/hardwareswap - Used hardware, swap hardware. r/buildapcsales - For sales on building a PC r/linux - All flavors of Linux discussion & news - not for the faint of heart!
