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 are five basic components of an accounting system?

There are five main components in an accounting system. Each part has a different job and accomplishes different step in the financial reporting process. The five components are source documents, input devices, information processors, information storage, and output devices.

What are the three basic components of an accounting information system?

The three steps of an accounting information system are input, processing, and output. Data is the raw ingredient used in these processes.

How many types of AIS are there?

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.

What are the AIS frequencies?

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.

There are two classes of shipborne AIS – Class A and Class B. In addition, there are different types of AIS used for shore stations (AIS Base Stations), AIS aids to navigation (AIS AtoN), AIS on search and rescue aircraft and the AIS search and rescue transmitter (AIS- SART).

What are the main components of an automatic identification system?

The AIS system consists of one VHF transmitter, two VHF TDMA receivers, one VHF DSC receiver, and a standard marine electronic communications link to shipboard display and sensor systems. Position and timing information is normally derived from an integral or external GPS receiver.

What is class A and B AIS?

Class A AIS transponders (SOLAS Compliant) operate using Self-Organizing TDMA (SOTDMA) broadcast mode and transmit at a power level of 12.5 watts. … Class B AIS transponders operate using Carrier-Sense TDMA (CSTDMA) broadcast mode and transmit at a power level of 2 watts.

What is AIS base?

The AIS base station is the primary component in an AIS physical shore station, and the most important component in a coastal AIS network. Our AIS base station receives and communicates AIS data from all AIS sources (AIS mobile stations, other AIS base stations, AIS aids to navigation units etc.)

What is difference between Class A and B AIS?

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.

What is the maximum range of AIS?

AIS enables authorities to reliably and cost effectively monitor fishing vessel activities along their coast line, typically out to a range of 100 km (60 mi), depending on location and quality of coast based receivers/base stations with supplementary data from satellite based networks.

What is the difference between AIS and VMS?

VMS and AIS are considered line-of-sight systems, VMS having the advantage of having receiving antennas on satellites requiring only that both the transmitting and receiving site are within range of the same satellite thus having a long range potential, while AIS (currently) relies upon ship-to-ship or shore- to-ship …

What is a Class A vessel?

Class A Vessels: These classes of vessels have less than 16 feet in length. Class I Vessels: These classes of vessels range from 16 feet to no more than 26 feet in length. Class II Vessels: These classes of vessels range from 26 feet to no more than 40 feet in length.
