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.

A fixed set generally has the advantages of a more reliable power source, higher transmit power, a larger and more effective antenna and a bigger display and buttons. A portable set (often essentially a waterproof, VHF walkie-talkie in design) can be carried on a kayak, or to a lifeboat in an emergency, has its own power source and is ...
Overview diagram of COSPAS-SARSAT communication system used to detect and locate ELTs, EPIRBs, and PLBs First generation EPIRB emergency locator beacons. An emergency position-indicating radiobeacon (EPIRB) is a type of emergency locator beacon for commercial and recreational boats, a portable, battery-powered radio transmitter used in emergencies to locate boaters in distress and in need of ...
The radar antenna itself is described as being 384 m 2 (4,130 sq ft). It has 45,000 [3] solid-state transmit-receive modules mounted on an octagonal flat base which can move ±270 degrees in azimuth and 0 to 85 degrees elevation (although software currently limits the maximum physical elevation to 80 degrees). The maximum azimuth and elevation ...
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 ...
The TIS will have 1–9 interrogators (remotes) scattered throughout the range. One of these remotes is at the TIS, and is referred to as the "remote at Master". Each remote interrogates an AIS pod (see below) loaded on each aircraft flying on range, and receives the response and relays it to the TIS. [1] Airborne Instrumentation
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.
