What type of antenna the earth station can use?
Parabolic reflectors
Earth Station Antenna Parabolic reflectors are used as the main antenna in earth stations. The gain of these reflectors is high. They have the ability of focusing a parallel beam into a point at the focus, where the feed system is located.
What is earth station antenna?
Earth stations consist of a reflector antenna (or parabolic dish), a feed system to send and receive the RF carrier, data handling equipment and mechanical tracking equipment to keep the satellite within the antenna’s data send/receive area. …
How does an earth station works?
Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands (e.g. microwaves). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link.
What are the different types of antennas for the satellite and earth station?
The different types of antennas used in satellite communication are as follows:
- Horn Antenna.
- Parabolic Reflector Antenna.
- Parabolic Reflector Antenna with offset feed.
- Double Reflector Antenna.
- Shaped Reflector Antenna.
Which type of antennas are most commonly used for the satellite?
Horn antennas. The reflector antenna is most frequently used in communications satellites because of its simple structure, light weight, and high gain (Fig.
What are the basic requirements of earth station antenna?
Earth stations operating in the band 13.75 – 14.00 GHz shall have minimum antenna diameter of 1.2 m. For earth stations within the fixed-satellite service having an antenna diameter greater than or equal to 4.5 m, the EIRP of any emission should be at least 68 dBW and should not exceed 85 dBW.
What are the requirements of earth station antenna for satellite communication?
1. Large antennas required for transmit and receive on the INTELSAT type global networks with gains of 60 to 65dBi (15 to 30 metres diameter). 2. Medium sized antennas for cable head (TVRO) or data receive only terminals (3-7 metres diameter)
What is the use of satellite earth station?
A Satellite Earth Station is a type of radio equipment used to communicate with a space station (satellite) from the Earth’s surface. They are typically used to provide telephony, data, backhaul, broadcast feeder links and two-way business/consume broadband or corporate type communications.
Which antenna is used in satellite?
Four main types of antennas are used on present communication satellites: wire antennas, horn antennas, reflector antennas, and array antennas. Wire antennas were used on the early operational satellites such as INTELSAT I and II with an antenna gain of about 4 dBi for receive and about 9 dBi for transmit.
What’s the difference between antenna and satellite?
They use different methods to get programming on a TV. For instance, aerials pick up special radio waves emitted by television stations. The type of waves that will be received and the range is closely related to the aerial. On the other hand, satellite TV picks up radio signals from satellites located in the orbit.
What are the key performance parameters of an earth station explain?
The performance of a receiving earth station depends on a number of factors. The most important of these are the receiving antenna gain and the low noise converters noise figure. If all else is equal designers can make trade offs between these factors and achieve equal performance.

How big is an Intelsat earth station antenna?
Typical values are 40.7dBK −1 for an INTELSAT A, 30 metre diameter antenna operating at 4/6GHz (Pratt, 1986) Large earth station antennas are expensive to construct and to maintain so that there is a premium in obtaining the maximum efficiency from the system.
