Frequency band in use for satellite transmitiones
Today satellites do not use only the Ku and C
band but also other band to emit.
Most of these bands aren’t used for TV program
and radio program emitting, but for special causes: i.e. emitting
signals for military purposes- military satellites, emitting signals
for communication- Inmars satellites, bands used by meteorological
satellites- Eumetsat, etc.
All satellites use two frequency bands. One is used for the uplink-
sending the data to the satellites, and the other one for the
downlink-sending data to the earth. We will now name the bands
that are used.
| Band name |
Frequency range |
User |
| L - band |
1530 - 1650 MHz |
Inmarsat, air and sea traffic. Meteorological
serveces. |
| S - band |
2535 - 2655 MHz |
Downlink[i] for comunication satellites. For
example Arabsat and Insat. |
| C - band |
3700 - 4200 MHz |
Downlink for comunication satellites. Most satellite
in America, Asia and Africa. |
| C - band |
4500 - 4800 MHz |
Downlink for military satellites. |
| C - band |
5900 - 7000 MHz |
Uplink[ii] for military and comunication satellites.
|
| X - band |
7200 - 7750 MHz |
Military satellites, Nato. |
| X - band |
7900 - 8400 MHz |
Uplink military satellites. |
| Ku - band 1 |
10.700 - 11.750 GHz |
Downlink for FSS [III] |
| Ku - band 2 |
11.750 - 12.500 GHz |
Downlink DBS [IV] |
| Ku - band 3 |
12.500 - 12.750 GHz |
Downlink for Telecom [v] |
| Ku - band |
12.750 - 13.250 GHz |
Uplink for telecomunication satellites. |
| Ku - band |
14.000 - 14.800 GHz |
Uplink for telecomunication satellites. |
| Ku - band |
17.300 - 18.100 GHz |
Uplink for telecomunication satellites. |
| Ka - band |
18.300 - 21.200 GHz |
Rarely used. Kopernicus satellites have one
of these transponders. Used for some transmisiones. In the
future it will be more in use because the whole KU band will
be used completly. |
| K - band |
27.500 - 31.000 GHz |
Uplink for future telecomunication satellites. |
