VSAT has increasing demand in the maritime environment
VSAT technology is a way to establish two way satellite communications to enjoy internet, telephony and data in far flung areas and harsh environments. Herein, this is particularly for marine environment.
Usually, VSAT solutions in the maritime segment are offered as packaged solutions comprising – satellite space segment, equipment, phone and internet services. For commercial markets, VSAT services have operated at Ku-band and C-band, and by making use of satellites placed at GEO orbital location. The location of the satellites coupled with the movement of the vessels, one needs stabilised antennas and tracking. A stabilised maritime VSAT antenna typically consists of circular antenna with a diameter of 2.4 metres or smaller. The majority of VSAT antennas range from 60cm to 1.5 metres in diameter for Ku-band and 2.4 metres (or even larger) for C-band.
Normally, the data rates range from 64kbps up to 8Mbps, but you can also have lower and much higher data rates. A remote maritime system typically has two parts –
An outdoor unit or an antenna and transceiver placed outdoors. In maritime, this can also be termed as ‘Above Deck Unit or ADU’
An indoor unit is there to react with the outdoor unit and control the antenna. In maritime it is also known as ‘Below Deck Unit – BDU’
In line with the increase in popularity of VSAT systems in the past few years, a quite interesting shift has appeared to the horizon as many operators have started to establish themselves in market to offer this facility. C and Ku bands are already being used for offering the services, but Ka band has also been introduced to the market. It is based on the iDirect technology. This new technology is supposed to offer seamless global coverage and extraordinary mobile broadband with a higher speed.
iDirect Broadband VSAT network system ensures highly reliable and secure two way data transmission at a higher speed for multimedia service applications. Easy connectivity is ensured in any data network with an integrated satellite modem and router with Ethernet surface, further combined with IP architecture.
Seeing their popularity and high demand in the maritime environment, VSAT providers are continually expanding their wings and advancing their technologies to drive growth. Their endeavour is to drive growth to meet the continually increasing demands for more bandwidth with smaller antennas. iDirect service with VSAT is a highly advanced technology for the maritime industry and the kind of environment they are supposed to perform. The technology allows them to stay connected with the rest of the world even in the middle of the sea.
