Artificial Satellites

1. Weather forecasts

2. Television (other than local news, and some of that is satellite-delivered as well)

3. Intercontinental telephones

4. The Internet

5. Anything that uses GPS, including airlines, UPS or FedEx drivers, campers

6. The military; almost all military communications are sat-based.

Yes. The planet Uranus is "tilted" in its axis of rotation, with its North Pole facing almost directly toward the sun. Many of its moons would be visible throughout most of their orbits, since they are seen looking "down" from "above them". If the planet were not so cold (sometimes within 60° C of absolute zero), the effect of the Sun heating ONLY the northern hemisphere of the planet would create unique weather patterns, to say the least.

You would need at least three GPS satellites to pinpoint your location. However, you would need a fourth to also identify your elevation.

The first man-made satellite was Sputnik, launched into orbit in 1957 by the Soviet Union. The first American satellite was Explorer, launched the following year.

The oldest satellite still in orbit is Vanguard, launched in 1958 by the US.

There are now thousands of satellites currently in orbit, including communications satellites, GPS satellites, and the International Space Station.

if you would like to see a real-time 3-D plot of satellites now in orbit, check out the JTRACK 3D web site from NASA.

The salary of a satellite command and control operator can vary depending on factors such as experience, location, and specific employer. On average, they can earn between $60,000 to $100,000 per year.

This can vary depending on the function of the satellite. In general, the satellite is launched by unmanned rockets or from the space shuttle payload bay at the correct altitude. After the satellite is released from the launch vehicle, the speed of a satellite is adjusted so that the rate at which it is being pulled back toward the earth is the same as the rate at which the earth is turning underneath it. So it is continually falling but not hitting the earth. This is what is also happening to the space shuttle when in earth orbit and the ISS.

Satellites in geostationary orbit - where they appear to remain over a single point on the earth - must have a circular orbit for this to occur. That is why they are placed over the equator. Any other orbit is elliptical in shape.

The problem that arises is that the earth is not perfectly round, even at the equator, and so the orbit of geostationary satellites must be adjusted every two weeks to compensate for this. The engines are remotely fired for the correct amount of time. When the fuel runs out, this can no longer be done.

Orbital mechanics is a complex and detailed concept to understand. See some of the Web Links to the left.

Planetary satellites are made up of a variety of materials, including rock, ice, and metals. The composition can vary depending on the size and location of the satellite. For example, moons of gas giants like Jupiter and Saturn tend to be composed of ice and rock, while smaller asteroids and comets that act as satellites are made up of rock and metal.

If you mean man-made satellites ... Traditionally the main structure has been made of aluminum, although many now are some sort of composite. Usually it's some sort of graphite fiber-polycyanate face sheet over aluminum honeycomb, though it varies a lot by manufacturer and application. Polycyanate is preferred to epoxies for the matrix because it doesn't shrink as much when it loses moisture. There's a lot of other stuff in there. Propellant tanks are usually titanium, while other propellant components like lines and engines are typically steel. Housings for electronics are usually aluminum.

Satellite communication involves the use of artificial satellites in orbit around Earth to facilitate communication between different points on the planet. These satellites receive signals from ground stations, amplify them, and then retransmit them back to Earth. This technology enables a wide range of applications, including television broadcasting, internet connectivity, and global positioning systems. Satellite communication is crucial for connecting remote locations, disaster relief efforts, and providing communication services in areas with limited infrastructure. However, challenges such as signal latency, signal interference, and high costs persist in satellite communication systems.

Satellites use a variety of imaging techniques, including visible light, infrared, and microwave imaging, to monitor weather patterns from space. These images help meteorologists track cloud cover, precipitation, temperature, and other weather features around the globe in almost real-time.

I haven't get the correct names of the satellites that Indian Government is going to launch but i know they go to launch satellites regarding

"GLOBAL POSITIONING SYSTEM".

The Government is going to launch around 7 satellites by 2010.

The Indian Government wants to develope its own GPS.

Now the GPS is under the control of U.S.Government,it has around 20 satellites of its own.

The Russian Government has around 24 satellites.

There may be as many as 25,000 artificial satellites orbiting Earth, although only around 8,300 are on record and less than 5000 are active. Our planet has only one natural satellite, the Moon.

The name of the second satellite can vary depending on the context. It could be any specific satellite's name, such as "Hubble Space Telescope," "GPS satellite," or "ISS (International Space Station) satellite."

There is an orbit called a geosynchronous orbit (GEO), which is a satellite that travels around the Earth in the Earth's exact speed, so it's always in the same position as the Earth. GEOs are used for communication nowadays, and so ground stations are always in contact with the satellites. That means that your T.V. programs and phone calls are never interrupted! :D

A rocket has three parts all have tanks containing rocket fuel and oxygen. The first part lauches from earth than the secon part brings you closer the the targerted spot in space, The oxygen is needed because spase has no oxygen. Later the second part is released than the top containing the people is left with enough fuel to finish the job.

India has the best spy satellite...... Most people do not know this..........

i dont know. i dont even know what a moral issue is!

Generally unguided rockets used as weapons do not travel as far as missiles, which is the term for guided weapons. Rockets used as fireworks only travel a few hundred feet vertically. Model rockets may reach a height of a mile or more. Rockets used to launch satellites propel the payload above the atmosphere, which expends most of their fuel.

Because satellites lack the geographic constraints of terrestrial systems, they are better suited for long-distance, point-to-multipoint transmissions such as television broadcasts

satellite should be at least 42000Kms from center of earth .As the radius of earth is around 6370Kms ,the height reduces to 35000Kms.

This code is an International Network, which called ( International Telecommunications Union (ITU) ).

One of the folowing services have +8821 Code:

+8821 10 British Telecommunications plc ( Global Office Application )

Note: These serviceses are very expensive !

satellite communication is used for long distance communication, in this signals are transferred from landlines to station , station to satellite and then satellite to station , station to destination.

while bts is used for short distance communication with help of bts towers and range of bts towers lies between 8-15km.
