Installation and commissioning of VSAT equipment as part of the Gazpromneft Nord-West project.

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

What is LNB?

The acronym LNB stands for Low Noise Block. This device is installed in front of a satellite dish, which receives a very low signal and amplifies it, changes the signal to lower frequencies and transmits them via cable to the receiver.
The expression Low Noise refers to the quality of the first transistor preamp. Quality varies in units designated as “noise temperature” or “noise figure”. The lower the noise temperature, the better. So, LNB with a noise temperature of 100 K is twice as good as – 200K. C-band LNBs typically have the lowest noise temperature, and Ka-band LNBs have the Continue reading

What is a BUC?

The basic architecture of a conventional satellite terminal is based on the historical desire to make the most open and free construction. Over the years, this concept has developed global competition in creating the functionality of hardware units, and as a result, the architecture has improved and costs for the end user have decreased.

However, since operational requirements have changed and technology has improved, it is also necessary to change the system architecture in order to achieve additional benefits. The CPI amplifier with an integrated L-band frequency converter (BUC) allows you to reduce costs and increase the reliability of data transmission at low and medium frequencies by eliminating duplicate functions in a conventional RF terminal circuit.
