AIS is intended to assist a vessel's watchstanding officers and allow maritime authorities to track and monitor vessel movements. AIS integrates a standardized VHF transceiver with a positioning system such as a Global Positioning System receiver, with other electronic navigation sensors, such as a gyrocompass or rate of turn indicator. Vessels ...
Maritime identification digits are used by radio communication facilities to identify their home country or base area in digital selective calling (DSC), Automatic Transmitter Identification System (ATIS), and Automatic identification system (AIS) messages as part of their Maritime Mobile Service Identities.
This contrasts to the Automatic identification system (AIS) used globally on ships that transmit continuously. A short post-transmission message is sent by the radio with the vessel identity and is in the form of an encoded call sign or Maritime Mobile Service Identity , starting with number "9" and the three country-specific maritime ...
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.
Automatic Identification System (AIS) is one of the most important sources of data for the MDA agencies. AIS is used in order for ships to know each other’s whereabouts, they transmit a signal from ship to ship and to shore. Lately, the system has been developed into satellite system, so called satellite AIS, which makes the system more ...

The lingering effects of a high pressure system will conspire with an approaching storm from the Midwest to make a mess across much of the East.
“When you’re bitten, the tick transfers that molecule, galactose-α-1,3-galactose, to the body,” explains William Schaffner, M.D., an infectious disease specialist and professor at the ...
