AIS-SART was added to Global Maritime Distress Safety System regulations effective January 1, 2010. [22] AIS-SARTs have been available on the market since at least 2009. [23] Recent regulations have mandated the installation of AIS systems on all Safety Of Life At Sea (SOLAS) vessels and vessels over 300 tons. [24] Accident investigation
The Antenna Interface Standards Group (commonly referred to as AISG) is a non-profit international consortium formed by collaboration between communication infrastructure manufacturers and network operators with the purpose of maintaining and developing a standard for digital remote control and monitoring of antenna line devices in the wireless industry.

AIS receiver station receive telegrams from near by vessels via VHF data (about 162 MHz) and sending it to Automatic identification system to be recorded and used for ...
An amateur radio installation on a 28' yacht, including 100W HF transceiver with microphone, manual antenna tuner, and morse key. Maritime mobile amateur radio is an amateur radio transmission license that allows maritime operators to install and use radio while they operating at sea. The call sign of operators is extended by adding the suffix ...
VMS components on the vessel sometimes are called VMS, or sometimes Automatic Location Communicators (ALC). These minimally include a GPS antenna and receiver, a computer (which may be embedded or user-supplied), and a transmitter and antenna appropriate for the communications that links the vessel to the flag center.
Thus the information collected from the two systems, S-AIS and LRIT, are mutually complementary, and S-AIS clearly does not make LRIT superfluous in any manner. Indeed, because of co-channel interference near densely populated or congested sea areas satellites are having a difficult time in detecting AIS from space in those areas.
Antennas are generally sensitive to signals only when they have a length that is a significant portion of the wavelength, or larger. Most antennas are at least 1 ⁄ 4 of the wavelength, more commonly 1 ⁄ 2 – the half-wave dipole is a very common design. For longwave use, this resulted in loop antennas tens of feet on a side, often with ...
Radio transmitter with a label indicating it will identify any transmisssions from it as coming from "PF7297" using the ATIS protocol [1] The Automatic Transmitter Identification System (ATIS) is a marine VHF radio system used and mandated on navigable inland waterways in Europe for identifying the ship or vessel that made a radio transmission.
