How do I get data from AIS?

To receive all AIS transmissions a receiver must monitor both channels simultaneously, so the receiver must in effect be two receivers in one box. If two separate and different transmissions arrive at the receiver at the same time but on different channels both transmissions will be received and output by the receiver.

What is AIS ship data?

The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). AIS is intended to assist a vessel’s watchstanding officers and allow maritime authorities to track and monitor vessel movements.

Can you see ships on Google Earth?

If Google Earth is installed in your computer, you may see the vessels positions in real time and you may browse quickly the areas of your interest, without the limitations of the web page maps but just using Google Maps.

How accurate is AIS data?

Currently, there is no mechanism to ensure the authenticity of AIS data and the tracking facilities and authorities should work together to ensure certainty that the originator of the data is known and that it is 100 per cent accurate.

How do I know if my AIS is transmitting?

If you get green across the board then the unit itself is transmitting. Note if you don’t get a check for TX position reports then check to see you have a valid GPS signal. The unit will not transmit unless it has a valid GPS position.

Is AIS and MMSI the same?

Automatic Identification System (AIS) has become an important element of the GMDSS monitoring system because of its ability to provide immediate and accurate contact between vessels. The AIS uses the same MMSI number assigned to the vessel for GMDSS purposes, enabling coordinated communication.

What is AIS and its function?

The Automatic Identification System (AIS) is a system used by ships and Vessel Traffic Services (VTS) principally for identification and locating vessels. AIS provides a means for ships to electronically exchange ship data including: identification, position, course, and speed, with other nearby ships and VTS stations.

What is AIS and its uses?

The automatic identification system, or AIS, transmits a ship’s position so that other ships are aware of its position. The International Maritime Organization and other management bodies require large ships, including many commercial fishing vessels, to broadcast their position with AIS in order to avoid collisions.

How can I track my ship at sea?

Can Titanic be seen on Google Earth?

Now, despite its depth on the sea floor, you can explore this ill-fated ship from the comfort of your home using Google Earth. Explore different parts of the ship, from prow to stern by simply searching for “Titanic” in the Google Earth search box.

What is the range of AIS?

about 40 nautical miles
The AIS signals have a horizontal range of about 40 nautical miles (74 km), meaning that AIS traffic information is only available around coastal zones or in a ship-to-ship zone. AIS communication takes place using two VHF frequencies, 161.975 MHz and 162.025 MHz, using a bandwidth of 25 kHz.

What is the range of Class B AIS?

between 8-10 miles
As the units are not interfaced with a compass, heading information is rarely transmitted. The main difference between Class A and Class B units is the power output, Class B transmits at 2W, giving a range of between 8-10 miles, whilst Class A transmits at 12.5W giving a much larger range.
