Mainly because of the curvature of the Earth. If you want to send a signal from one city to another 300 kilometres away by aiming directly at that city, it would end up travelling through the ground as the planet curves which would cause a loss of signal. By sending it to a satellite, both cities have a clear line of sight and as a result, there is very little signal loss.

What is a sateliette?

It seems like you may have mistakenly combined "satellite" and "planet" to create the term "sateliette." A satellite is a natural or artificial body that orbits around a planet, while a planet is a large celestial body that orbits a star.


What are bodies that orbit moons or planets called?

Bodies that orbit moons or planets are called natural satellites or moons. These satellites can be relatively small bodies like asteroids or large bodies like moons, depending on the size and characteristics of the object. Some planets, like Earth, also have artificial satellites created by humans for various purposes.


What is the difference between moon and satellite?

The moon is a natural satellite that orbits a planet, while a satellite is an artificial object placed into orbit around a celestial body by humans. Moons are typically larger than artificial satellites and have natural origins, such as forming from debris around a planet.


When were satellites invented?

In 1957, the Soviet Union launched Sputnik, which was the first man-made satellite.The first satellite was Sputnik 1, launched on October 4, 1957.Sputnik is the first publicly recognized artificial satellite, but there are large rumors (but obviously no confirmation for this is classified information) that the U.S. launched a modified V-2 rocket in 1948.in 1957Sputnik 1 was the first satellite. It was launched by the former Soviet Union in 1957.The first satellite put into orbit was a Russian satellite called sputnik. It was put into orbit on 10/4/1957.


Earth is orbited by a large what?

Earth is orbited by a large natural satellite known as the Moon.

What year did television start having satellite?

The first satellite television transmission was sent from Europe to the US via Telstar in 1962. Although amateur home satellite systems (requiring very large dishes) debuted in 1976, their legal status was in flux until the passage of the Satellite Home Viewers Act in 1979. The first DBS system (what we use now) was Primestar in 1991 followed by DirecTV in 1994 and Dish in 1996. Satellite signals for TV began in 1962. The satellite signal was from Europe to Telestar Satellite over North America. The first national satellite network originated in the Soviet Union in 1967. The first domestic Noth America satellite was produced in 1972.


Where can I buy an HD satellite dish?

You can usually get an HD satellite dish from your satellite company. Direct TV or Dish Network are two large companies that are available in almost every area. They have HD satellite dishes. www.dishnetwork.com


Can home satellite tv be used mobile ie motor home?

It could be done, but if you have the really large satellite dishes, you'd have to find something a bit more travel friendly. You'd want the tripod mount for the satellite.


How do employees on offshore oil rigs send email?

Satellite communications. Installation operators will pay a large fee for a set bandwidth to be shared between the crew for email, internet access, telephone and sometimes television, but the latter can be direct from a satellite television provider.


What happens with satellite TV when there is a sun outage?

The Sun is the prime energy source for the planet earth. It burns and gives the planet light every day. The sun never goes out, but at certain times during the orbit of the satellite, the sun will affect how the satellite transmits. This is called a "sun outage" Sometimes, the sun will release large plasma masses called Coronal Mass Ejections, and these events may disrupt satellite TV. Satellite TV interference is common due to solar radiation, solar wind, and CMEs.


Which are the applications of vestigial sideband?

Vestigial Sideband Transmission is used for the transmission of Television signals.Because the video signals need a large transmission bandwidth if transmitted using DSB-FC or DSB-SC techniques.


What 's the difference between satellite and terrestrial?

Satellite communication involves transmitting signals to and from an artificial satellite in orbit around the Earth, while terrestrial communication uses ground-based infrastructure like cables, fiber optics, and antennas. Satellite communication can cover large distances and is often used in remote areas, while terrestrial communication typically offers faster speeds and lower latency for more localized communication.


Are old satellite dishes worth any money?

They are a valuable commodity, as they have a number of different uses. They can be used to broadcast wireless networks over a large area. They can also be used to receive Free-to-Air satellite TV when properly retrofitted.


What were satellites originally made for?

The first artificial satellite that had a particular purpose (other than just for scientific research) was the Echo satellite; a large mylar balloon placed in orbit to reflect radio signals back to the Earth. Now, satellites are used for all kinds of communications; TV, cell phones, overseas phone calls, internet and such; weather satellites that help to predict the weather and track storms, and reconnaissance satellites that take photos of the Earth. Oh; GPS satellites.


Is satellite tv service gaining market share on the cable companies?

In 2009, satellite TV actually lost market share to the large cable companies. This is likely due to the lagging economy. Many cable companies offered great packages in 2009 in order to keep adding new customers.

Why do local broadcast television stations have so many large satellite dishes?

Broadcast television stations are heavily reliant on communication with other television production organizations and content delivery companies. Although land based communications are becoming ever faster, the television industry has been built on satellite communication systems due to the very mobile nature of news and event gathering production units. Live news feeds can be obtained from almost anywhere in the world with a satellite transmission. The signal can be transported around the world an back to base stations with ease. TV stations use several satellites for incoming and outgoing signals, hence the array of dishes, all of which can be active at any time. Unlike domestic satellite dishes, commercial dishes need to be capable of receiving low power transmissions from satellites that are not always in ideal locations. The large size of the dishes allows higher signal levels to be captured, from satellites that many be low in the sky and also overcome the problem of weather related dropout occasionally experienced by residential dishes.
