VSAT satellite communications technology has been successfully used to organize communications in geographically inaccessible areas, as well as areas with poor infrastructure without mobile coverage. On the ground, VSAT is, first of all, a satellite station with an antenna of no more than 2.5 meters in diameter. This equipment standard appeared in the sixties when a new satellite telephone network was successfully tested in Alaska. Today, VSAT implements sustainable telephone channels and broadband data. VSAT helps organize distance events in those cases where traveling to the place of all participants is not economically feasible. This training programs, and meetings, and video conferencing remote units of commercial or government agencies. Convenience of VSAT consists mainly in simplicity of system Continue reading
Providing telephone communications to remote mobile objects is essential for many modern organizations. Despite the systematic increase in coverage of mobile networks of the main operators, there are still quite a lot of areas where there is no communication as such, and the only thing that can really guarantee communication is satellite technology. On the other hand, IP-telephony is increasingly prevailing over analog standards due to its cost, functionality and simpler structure.
One of the distinguishing features of IP-telephony is the use of technologies and data transfer formats using communication protocols standard for Ethernet technology. Such optimization allows, among other things, to reduce the volume of the data stream, and to use at the same time more communication channels. One of these channels, geographically more advantageous, is a satellite communication Continue reading
The customer set the task of installing the VSAT KNS Z12 system on the tanker-bunker vessel type Gazpromneft Nord-West, with tuning and commissioning. The customer selected the VSAT KNS Z12mk2 antenna system itself, as well as the telecom operator, tariff and connection conditions.
installation of vsat system The installation of a small satellite ground station VSAT on a ship is carried out in the following sequence:
coordination with the customer of the installation site;
preparation of the project and its coordination with RMRS on installation;
manufacturing power fasteners;
installation of the antenna system itself; Continue reading
Over the past 15 years, means of satellite Internet access have been rapidly developing on the high seas, beyond the reach of coastal communication networks.
For yachts and small vessels, dial-up became the first available – connection via satellite phones Globalstar, Inmarsat Mini-M, Iridium, Thuraya.
The cost of communication was high, the speed was measured not in megabytes, but in kilobits per second. Later VSAT compact (with a diameter of half a meter) antennas appeared, working with various Ku-band satellites; channel capacity reached 1 Mb / s, with the ability to transfer large volumes. Apart from a slight signal delay due to the large distance from the terminal to the satellite, Internet browsing Continue reading
The article considers the current state of affairs in the maritime satellite communications market and forecasts Euroconsult specialists for the next 10 years.
Increasing consumer demand, a new generation of satellite technology and increasing competition among operators may result in VSAT services occupying about 70% of the maritime satellite communications market in less than 10 years, experts at Euroconsult say. Continue reading
