The following describes the commonly used vertical polarization (V) and horizontal linear polarization (H) receiving methods.
The reception of vertical polarization and horizontal polarization is determined by changing the direction of the rectangular waveguide feed port. When the long side of a rectangular waveguide is parallel to the ground, it receives vertical polarization, and when it is perpendicular to the ground, it receives horizontal polarization. The polarization direction (polarization angle) varies from place to place. Because the earth is a sphere, but the downlink beam of satellite signals propagates along a horizontal straight line, which causes the same polarization signal received at different azimuth angles to be different, so the polarization direction of signals received at different geographical locations is also different. FEC, also known as forward error correction, is a very important data. In early digital computers, such as NOKIA9500, FEC parameters need to be input. Only later, the operation speed of the digital computer was improved, and FEC could be measured automatically without the user's own input of FEC parameters. However, FEC is still an indispensable parameter in the decoding process of digital programs. This is just like today's blind scanner with faster operation speed can receive programs without inputting parameters, but the downlink frequency and symbol rate are still the most basic program data. In digital signal, in order to prevent external signal interference and protect the signal from changing, multiple error correcting codes should be set. In the process of decoding, digital signals are very sensitive to error signals. As long as there are very small errors every second, it can't be decoded normally. The smooth playback of digital satellite signals is due to the setting of error correction codes in digital signals. Among all kinds of error correcting codes, FEC is a very important anti-jamming algorithm. The FEC method of forward error correction is used to reduce the bit error rate of digital signals and improve the reliability of signal transmission.
For example:
Downlink frequency polarization symbol rate
12406 vertical 30000 3/4
In this set of data,
Downlink frequency is 12406.
Polarization is (V)= vertical (h) stands for horizontal.
The symbol rate is 30000.
FEC means forward error correction.
The above is the explanation of satellite parameters. Please correct Yamal 202 49.0 E 20 10-03-30 daily update in time.
