It seems surprising to find out that the idea of communicating through a satellite was first described by an American clergyman and author. Edward Everett Hale wrote the concept in his short story titled ‘The Brick Moon’, published in 1869-70. The story tells the building and launch into the Earth orbit of a 60-metre-diameter brick-made satellite. The brick moon supported seafarers in navigation.
Later in 1945, a famous science fiction author Arthur C. Clarke introduced the first practical concept of satellite communication in a paper titled ‘Extra-Terrestrial Relays: Can Rocket Stations Give World-wide Radio Coverage’. His work led to the construction of the first satellite, Sputnik 1, launched by the Soviet Union on October 4, 1957. From there, the development of satellite technology continues.
The first VSAT (very-small-aperture antenna) came around in the early 1980s. It was a C-band receive-only type. During that same period, there was the introduction of the world’s first Ku-band VSAT to provide network connectivity for oil field drilling and exploration units. It was later followed by the development of the Ku-band VSAT for enterprise customers. These enterprise terminals expanded to 100,000 sites for the next 20 years. They are mainly used for two- way data or telephony applications.
VSAT is widely used because of its flexibility and easy deployment.
Communication is always an important part of every business. It is becoming more important in today’s digital age because digital transformation is taking place. Effectiveness and efficiency of business operations increase when applying digital solutions.
Some business sites and operation fields are located in remote places, especially at sea where conventional infrastructure is out of reach. A satellite offers borderless communication within its coverage area. With VSAT installed at a site, a network among workstations, operation fields, and offices can be established.
VSAT for maritime use has to endure in an extreme environment. A 3-axis stabilizer is an integral part for a maritime VSAT to always face the optimized direction for the best signal receiving. A dome is designed to cover for securing all parts. This allows VSAT to have low maintenance cost.
Further, the design of VSAT for the maritime industry is compact in size and is finely blended with the ship structure.
When ships or operation fields have VSAT, various applications are possible.
Maritime VSAT usage can be divided into two main aspects: business operation and crew & passenger welfare. There are more applications coming. Here are just some well-known examples.
An mobile application to help users monitoring their usage is exclusively included in the service from Ship Expert Technology. The service is a reliable and stable VSAT system for the maritime industry.
