The Automatic Identification System is designed for autonomous
information exchange between ship&ship and ship&shore-based
station. This information includes ships name, location, speed and
course over ground. Transas transponders also have a function which
allows operator to send binary and text messages from ship to ship,
from ship to shore and v.v. The exchange of information is realized
through two VHF channels.The transponders are working in broadcast
mode on shared channels, thus all transponder equipped vessels can
see each other. This exchange of information is performed fully
autonomously (without any involvement from a controlling station).
The broadcast data is received both by transponder equipped vessels
and shore based transponders.AIS TechnologySTDMA Datalink
AIS TechnologyThe transponders offered by Transas Marine include
functionality in accordance with the Technical Characteristics for
a Universal Shipborne Automatic Identification System, approved by
ITU (ITU-R M.1371). This means communication over two parallel VHF
channels, operation at the designated AIS 1 and AIS 2 channels and
radio transceiver approval in accordance with I-ETS 300 113.
On Board Transponder By installing a Universal AIS transponder
on a ship together with ECS or ECDIS system and other sensors,
surrounding ships equipped with a similar Universal AIS transponder
can be monitored in real time. The available voyage related
information includes:
Destination Estimated Time of Arrival Ships draught Type of
cargo
Navi-Harbour AIS Display
Base Station Transponder(SBT1000 Transponder)The base station
transponder is a standard 19 rack module that includes a standard
mobile transponder, power supply converter and DGPS reference
station/beacon receiver. With an installed reference station/beacon
receiver the base station transponder can broadcast different
corrections to transponders operating within VHF range. This
transponder is designed for land installations, both for
stand-alone units and network configurations.
