Satellite frequency bands
- L-band (1–2 GHz) Global Positioning System (GPS) carriers and also satellite mobile phones, such as Iridium; Inmarsat providing communications at sea, land and air; WorldSpace satellite radio.
- C-band (4–8 GHz)
- X-band (8–12 GHz)
- Ku-band (12–18 GHz)
- Ka-band (26–40 GHz)
Is AO 91 active?
AO-91’s U/v FM repeater is continuously available for use by amateur stations.
What is satellite beacon frequency?
Satellite beacons used for ionospheric research normally transmit in the VHF (30-300 MHz) or UHF (300 – 3000 MHz) bands.
What is range of C band?
C band (IEEE)
| Frequency range | 4 – 8 GHz |
|---|---|
| Wavelength range | 7.5 – 3.75 cm |
| Related bands | G / H bands (NATO) SHF (ITU) |
What frequency is NASA?
One of the frequencies we use is the same NASA used to beam TV signals from the Moon. That’s called S band (2–4 GHz), but we also use X band (8–12 GHz) and the Ka band (27–40 GHz). The earliest widely used DSN frequency was S band. Later added were X band and Ka band, which can send much more data per second.

What frequency does NASA use?
145.800 MHz It broadcasts on 145.800 MHz.
What frequency do astronauts use?
As mentioned above, the transceiver on board the ISS is tuned to transmit radio signals at a frequency of 145.80 MHz. “Anybody with a receiver or scanner able to tune into that frequency can listen to the space station when it’s overhead,” Ransom said.
Do satellites have beacons?
Most of the satellites have a beacon. They are normally at the top or bottom end of the frequency spread for that satellite. Some have two beacons.
What is satellite beacon receiver?
The iNetVu® BR400L 19” rack mount Beacon Receiver is a high performance unit designed to track the power density of a satellite beacon in real time. It supplies a DC voltage output that is linearly proportional to the strength of the beacon signal.
Why does the satellite use high frequency?
pfijk. The high frequency spectrum get wide bandwidth .
What is the frequency range of Satellite Radio?
Amateur radio. The Radio Regulations of the International Telecommunication Union allow amateur radio operations in the frequency range 1,240–1,300 MHz, and amateur satellite up-links are allowed in the range 1,260–1,270 MHz. This is known as the 23-centimeter band by radio amateurs and as the L-band by AMSAT .
What are frequency bands in satellite communication?
L-band (1-2 GHz)
What is cable TV frequency?
The UHF-band for television is the frequency spectrum between 300 to 1000 MHz. UHF covers over the air channels 14 (470MHz) to 69 (806 MHz) and analog cable TV channels 37(300 MHz) to 158 (1002 MHz). Digital Cable TV channels do not follow the standard analog channel allocation.
