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
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.

Equipment VSAT Internet and telephony allows you to get the usual communication service through a small diameter satellite dish. Just as some time ago mobile communications seemed to be something special, not intended for the mass consumer, VSAT satellite communications went the same way, providing satellite broadband Internet access and satellite telephony services to an increasing number of users. The development of VSAT technologies and their gradual penetration into the mass segment becomes possible due to lower prices for VSAT equipment and flexible pricing in the tariff line.

In addition to the land systems most in demand in remote regions with poor infrastructure, VSAT Continue reading
