Radio and television broadcast satellites: TOP 10 questions

The publicly available Lyngsat.com website provides information on satellites broadcasting over open communication channels.
Broadcasting and television broadcasting satellites.
This site contains enough information about each satellite to get answers to the most frequently asked questions about satellite broadcasting and satellite broadcasting.

Satellite Radio and TV Broadcast FAQ
1. What Russian radio stations broadcast via satellites?
There is all the necessary information about Russian radio stations broadcasting via satellites, as well as about the type of transmission (streaming or not), about which satellites are broadcasting, about the position of the satellite, the beam of this satellite, its radiation power. At the same time, the site navigation is made in such a way that you can get a more detailed answer on a specific issue by moving on.

2. Which satellites broadcast radio and TV?
The page provides information about the satellites broadcasting television and radio signals, their location, name and number. It also offers the option of choosing a region.

3. How to find out the polarization of a satellite? Circular or linear?
The satellite’s page provides information on its characteristics, for example, on the popular Eutelsat 36A / 36B, you can get the following data: in the first column you can see the broadcast frequency of a particular operator with the marks L, H, R, V, which means that the satellite is broadcasting in this frequency range with left rotation of circular polarization (L), or right rotation of circular polarization (R), or vertically linear polarization (V). Thus, this letter reports the polarization of the satellite beam:

Linear horizontal – abbreviated “H” (Horisontal).
Linear vertical – abbreviated “V” (Vertical).
Circular right – abbreviated “R” (Right).
Circular left – abbreviated “L” (Left).
4. What is the beam emission power (EIRP) of satellite television?
Also on the page in the first column, the last digits indicate the broadcast power in dBW.

5. What codecs are broadcasting from satellite?
Column 5 here indicates which codecs are used for broadcast transmission for a particular channel.

6. How to find out satellite coverage?
This resource also shows a satellite broadcasting map for each specific beam, for example, this page shows the broadcasting area of ​​Eutelsat 36A at 36.0 ° E Russia (Ku band) with an EIRP emission power in dBW, as well as the minimum mirror diameter necessary for this signal level antennas. And here the same information is presented in an interactive format.

Satellite broadcasting. Satellite TV channels (satellite TV).

7. What television channels do satellites broadcast?
On the example of Tricolor TV, frequencies, codecs, radiation power and directly channels with the identifier of the service, audio and video stream are presented.

8. Which satellites broadcast the TV signal in HD quality?
This resource contains satellites that can broadcast in HD quality, for example, in Europe.

9. What is the diameter of the antenna mirror for high-quality reception of satellite television or radio signals?
Depending on the location of the receiving antenna system or on the territory in which it will be moved, it is possible to choose the diameter of the mirror. Using the example of the Eutelsat 36A at 36.0 ° E beam operating in the western territory of Russia, the radiation power is shown, and a graph of the correspondence of the signal level of the beam and the diameter of the mirror is shown below. Practice shows that to get a better signal from the specified EIRP it is better to subtract 1 dBW.

10. What television and radio companies from Russia broadcast in the satellite broadcasting grid?
The entire list can be viewed here. At the same time, when you click on specific companies, you can get information on which satellites they broadcast.
