The main trends in the development of marine satellite dishes

The increase in the volume of data transmitted from ships to shore means for shipowners and managers the need to upgrade satellite communication antennas to more powerful ones. Today, VSAT marine antennas have low power supplies of about eight watts or less in order to maintain their low weight. This is enough to connect the VSAT equipment operating in the transmission mode of the standard downstream ship traffic, but not enough to increase the upstream traffic transmitted from the ship to the satellite.

In order to adapt the equipment to higher data rates on the uplink, antenna manufacturers can install high power supplies, which leads to an increase in the total weight and size of the antennas. However, Cobham Satcom has developed a 20-watt power supply with the same dimensions and weight as the 8-watt one. The device was included in the high-power version of the Cobham Satcom Sailor 900 VSAT equipment. Continue reading

What is an active antenna and passive antenna?

Thanks to the dynamic development of television broadcasting in the modern world, there is probably no person who does not encounter antennas. In order to watch their favorite TV shows in the best quality, the user needs to connect the antenna to his receiving equipment. And then the question arises: which antenna to choose, active or passive? In this article, we will consider in detail the features of each antenna, as well as the scope of their application. But first of all, it is necessary to give a detailed definition of the very term “antenna” and briefly describe the history of creation.

Heinrich HerzAntenna is a special device whose main task is to receive or emit radio waves. It converts the fluctuations of the electric current into a radio wave or vice versa. As can be seen from the definition, antennas can operate on reception, transmission, or transmission. The simplest antenna operation Continue reading

Satellite tracker – an affordable means of security and control of moving objects

Global communications and monitoring with a satellite tracker – affordable satellite phone replacement
At a time when mobile phones had not yet become a mass product, pagers served as their more affordable alternative. And although with the help of a pager it was impossible to just talk, they coped with the task of transmitting important information perfectly. Today, mobile phones have completely replaced pagers both from markets and from our lives, however, if we take on global tasks, the paging principle itself remains very relevant, especially when it comes to travel that affects regions of our planet that are not covered by cellular networks. There will always be plenty of such places, because cellular networks appear only where a large number of users are able to recoup the created infrastructure, which means that in those places where real travelers seek, and where, by definition, there can not be many people, mobile will never appear communications, and, quite naturally, in all such cases it remains to rely only on satellite.

Without a satellite tracker as without hands
Currently, a satellite phone is still unavailable to a wide range of customers and to a greater extent remains a professional means of communication when labor productivity significantly exceeds the cost of satellite Continue reading
