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

The first batch of Iridium Next satellites is ready to launch

The first batch of Iridium Next satellites, the total number of which is 81, will soon leave the design base to go into space on SpaceX Falcon 9 missiles in September. The satellites will deliver in pairs in military trucks to Vandenberg airbase, where it will launch from September 11 to September 12 2016 year. This will be the third Falcon 9 flight from Vandenberg base and the first launch from there with a modernized version of the launch vehicle with more powerful Merlin engines and super-cooled rocket fuel. SpaceX will deliver a modified version to the launch pad at the end of summer.

The assembly of the first two Iridium Next satellites was completed last month and now Iridium plans to produce one satellite per week until the end of 2017.

“The release of one satellite per week is a truly impressive achievement in satellite production and something new that people will strive for in the future,” said Frank Culbertson, president of Orbital ATK, who oversees the final assembly of Iridium Next by agreement with the general contractor Thales Alenia Space.
