All tariffsVSAT subscriber terminal for two-way Internet
Two-way satellite Internet works through the VSAT (Very Small Aperture Terminal) terminal - a ground station satellite communications with an antenna of small (from 0.6 to 2.4 m) diameter. In modern satellite networks, this size is quite enough to organize a symmetrical Internet. Assembling the terminal does not require special skills, and given its low weight, the solution ensures high mobility and ease of work on the network. To connect to bidirectional satellite internet, you will need a VSAT small satellite earth station.
The standard subscription kit consists of:
- Antennas;
- Modem (channel-forming equipment);
- Transceiver device (2 W);
- Rod for attaching the transceiver device;
- Radio frequency cable with connectors;
- Supports for mounting the antenna;
- Grounding cable.
The most popular kits for two-way satellite Internet are terminals with antennas of 0.74m, 0.98m and 1.2m.
You can independently determine the parameters necessary to connect and configure satellite Internet by using the Satellite Finder.

The article discusses the issues of organizing two-way satellite Internet. Another name is duplex, synchronous. Geostationary satellites are used to operate such a system. This is a satellite located at an altitude of 35,768 km, its orbit (geostationary - GSO) lies in the equatorial plane, and the angular velocity of the device is equal to the angular velocity of the earth's rotation. Thus, it is always located above one point on the surface. This allows the use of fixed (fixed) antennas to transmit and receive signals from the satellite, which simplifies the process of information exchange. The satellite's position is constantly adjusted using propulsion engines. To survey the entire surface of the earth, 3 such satellites are theoretically sufficient, but guaranteed communication is carried out only in a 40-degree band on both sides of the equator. Communication up to 75-80 degrees is possible and feasible, but encounters certain technical difficulties. For Russia this is the Arctic.
The figure shows the Internet coverage area of two satellites:
Russian "Yamal";
Foreign "IntelSat".
As you can see, satellites provide communications to almost the entire territory of the Russian Federation, except for Chukotka, and also cover part of European and Asian countries
Compared to cable lines, two-way satellite Internet has a number of advantages:
Continuous communication, since the satellite and antenna are motionless relative to each other;
Independence from terrestrial cable and radio lines;
Coverage of a large surface with only three satellites;
There is no need for inter-satellite communication, as is the case with low-orbit systems where satellites exchange information.
There are also disadvantages to the operation of two-way satellite Internet:
High cost of satellite and receiving stations. This is determined by the large distance from the satellite (about 36,000 km) and, as a consequence, the low signal level.
Delay in signal propagation. Considering the speed of radio waves and the distance, the delay time is about 0.12 seconds one way, and the total response time is about 0.8 seconds. This is acceptable for television and radio broadcasting, but not always for the Internet, and game lovers need to forget about dynamic “on line” games.
Sensitivity to weather conditions (heavy rain or sleet with strong winds). This sometimes increases the delay time.
The principle of operation of two-way satellite Internet
In the case of synchronous Internet, the satellite operates in receive/transmit mode. The request from the client is transmitted to the satellite and then to the receiving station (provider), which sends it to the Internet. Having received the necessary data from the requested site, the provider transmits the information to the client via satellite. The exchange is carried out at microwave frequencies in the Ku band. Operation speed: up to 2 Mbit/s when transmitting and up to 8 Mbit/s when receiving information. The ground stations of the satellite two-way Internet client are called VSAT (VerySmall ApertureTerminal). VSAT stations can be stationary or mobile. The latter are widely used in the Ministry of Emergency Situations, on cars, ships, airplanes, etc.
Equipment, installation and configuration, tariffs.
There are many companies involved in installation and configuration. One of these is the RuSat company, which has been operating in this market for more than 10 years. The company has a transceiver teleport equipped with Ø9.15m antennas, powerful transmitters, backup power, etc. The basis is the Yamal satellite (Russia) and foreign IntelSats.
Below is a list of equipment supplied by the company for satellite Internet operation in two-way mode:
- Antenna Ø0.75m with automatic guidance.
- Transmitter with a power of 500 or 800 mW.
- iLNB converter. Converts the signal from the modem to the Ku band (reception, transmission).
- Modem with power supply.
- Equipment for orienting the antenna to the Point&PlayTM satellite.
- Cables with connectors. Ethernet (2 m, RJ-45) and two Tx and Rx cables (30 m, F-type connectors).
- Antenna support (optional).
- Documentation.
The subscriber can connect using tariff A (more than 1,350 rubles) or B (less than 1,350 rubles). If necessary, it is possible to connect to a local network via cable or Wi-Fi.
Two-way satellite Internet is the only option when high-speed cable or radio communications systems are not available. These could be dachas or cottage communities, remote villages, mobile facilities, etc.
Combination of two-way satellite Internet with local networks(cable or wireless) allows groups of users to connect to the network.
Satellites provide continuous 24/7 communications throughout the covered area.
Two-way (synchronous) satellite Internet works both for receiving and transmitting information from the satellite. It looks like this: the user makes a request to the Internet, the receiving and transmitting station processes the request and sends it to the satellite, from the satellite the request is redirected to the provider, then to the Internet, when a response is received from the Internet, incoming information from the provider’s server is sent to satellite, and from the satellite to the user’s computer (see diagram).
Scheme. Two-way satellite internet.
Thus, to work with two-way satellite Internet, there is no need to connect an additional channel for outgoing communication; the function of receiving and transmitting information is performed by satellite Internet equipment - the user’s receiving and transmitting antenna. This connection more reliable and stable, in contrast to a one-way type of access, because the user does not depend on failures in the operation of outgoing channels (GPRS on mobile phone, Ethernet, ADSL, Dial up), the request is instantly processed and transmitted to the satellite. This is the main advantage of two-way access.

Our company installs unlimited satellite Internet throughout the Moscow region. Such a connection will help you stay online even in places where the signal is from base stations mobile operators completely absent. Our technicians will quickly install the necessary equipment and select the optimal tariff based on your needs and financial capabilities.
A feature of satellite Internet is the relatively high cost of both the equipment itself and the services for its installation. A set of such equipment plus installation work costs approximately twice as much as a wireless connection.
It will also be expensive for the user unlimited tariffs, since you will have to pay for each Gigabyte of data received. In some tariff plans, you can immediately pay in bulk for a certain amount of traffic, and then pay extra for additional GB (and sometimes Megabytes). Thus, before connecting a specific tariff, you will need to estimate the upcoming traffic consumption as accurately as possible.
When connecting to satellite Internet, you will also have to face such a problem as speed limitation - from 5 to 40 Mbit/s for receiving and 5-10 Mbit/s for sending data (depending on the selected tariff plan). Moreover, what is meant here is the maximum possible speed, which in reality may be several times less. This can be affected by precipitation and heavy clouds, high congestion of data channels and many other technical nuances.
Moreover, due to high ping(signal delay time) with such an Internet network it will be impossible to work in real time. This is due to the fact that the satellite is at a very large distance from the earth, and it takes more than 600 ms for the signal to travel and process.
Due to the above problems, we install unlimited satellite Internet only in cases where there is no other choice (or as a backup communication channel). In most situations, we offer our clients a more profitable and stable 4G wireless network connection, which is much cheaper and provides significantly more opportunities.
