What is NMEA and AIS?

The National Marine Electronics Association Automatic Identification System (NMEA AIS, hereafter referred to as AIS) Reader provides FME with access to AIS messages that have been saved as a text or log file. Note: All AIS messages types are supported except for some of the binary message subtypes.

How do I get an AIS signal?

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 the maximum range of AIS?

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.

Why do ships turn off AIS?

A ship's crew may turn off its AIS broadcast for a variety of legitimate reasons, but this behavior may indicate that a vessel is hiding its location and identity to conceal illegal activities like fishing in no-take protected areas or entering another country's waters without authorization.

What is the difference between Class A and Class B AIS?

Class A AIS transponders are required to have a DSC (156.525 MHz) receiver, external GPS, heading, and rate of turn indicator, and can also transmit and receive safety-related text messages. Class B AIS transponders operate using Carrier-Sense TDMA (CSTDMA) broadcast mode and transmit at a power level of 2 watts.

What is AIS GPS?

An AIS transceiver uses VHF radio and GPS technology to communicate with other nearby ships. An AIS transponder determines its own position, speed and course using a built in GPS receiver.

How many types of AIS are there?

Types of AIS equipment.

For a shipboard fitting there are three types of AIS equipment, Class A, Class B and receive only. Class A is intended for vessels where the fit is mandatory. Class A transmits more information, more frequently and at higher power than Class B.

What frequency does AIS transmit on?

AIS transponders and receivers use two VHF radio frequencies: 161.975 MHz (AIS1, or channel 87B) and 162.025 MHz (AIS2, or channel 88B). The USCG has asked the Federal Communications Commission to authorize any US vessel to operate AIS on these two channels under its existing ship station license.
