Artificial Satellites

Which are usually launched in polar orbite and these polar orbit lie around north and south poles of earth and their angle with equitorial plane is 90'

Google has a constalation of 13 Satellites in orbit around earth for networking, mapping, and communication purposes. The first satellite, Google1, was launched on February 3rd, 2005 atop an Ares3 heavy lift vehicle from Launch Complex 32 at Kennedy Space Center in Florida. Subsequent Satellites were launched approximately every 3 months with the noted failure of Google 9 which was lost due to launch vehicle failure 78 seconds after launch. Google 10 was subsequently renamed Google 9 for consistency. Google plans to have a total of 23 Satellites in orbit by 2011 which some analysts suspect will allow them to offer a global internet option anywhere in the world as well as a world wide mobile phone system with their new Google Phone first offered to the public in 2009.

The most widely-known use for geo-stationary satellites - is the GPS system. There are sixteen geo-stationary satellites spaced evenly around the globe, to provide the data required by the GPS network to enable motorists to navigate safely throughout their journey.

Another use would be satellite TV. Satellites for TV broadcasting are usually orbiting in a fixed position, to provide a transmission 'footprint' on the surface of the earth.

For many reasons some being meteorology, communications, geographic mapping, spying, entertainment, and scientific studies of Earth and space.

Apollo 11 landed on the moon on July 20, 1969.
The landing was at 17:40 UTC (Greenwich Time)

Telstar 1 was launched on July 10, 1962
Telstar 2 was launched on May 7, 1963

Thousands each day. Most of them are tiny; the size of grains of sand or grains of rice. Only a few dozen per day are as big as a Baseball, and only a few per week are substantially larger.

The Soviet Union possessed superior rocket technology.

Some do. There are two types of orbits we use regularly. The first is Geosynchronous That is the satellite changes speed at exactly the same rate as our planet, so it appears that it doesn't move.

The second we use allot is polar orbits. This is a lower orbit that allows the satellite to see every point on the planet at regular intervals. We use these as spy satellites and for places like google maps.

It is possible to change a satellite's position by using other satellites in the same orbit, as landmarks. This is done by entering the four digits of the landmark satellite into a computer and then programming the satellite to change to that direction.

Natural satellites don't usually change position because for mankind to alter their orbiting path would be interfering. they occasionally change position due to their own cause.

Before Sputnik, America was in a "battle" with Russia on space flight. America wanted to be the first in space, on the moon, and have the first satellite orbit the Earth.

- When Sputnik (Russian Satellite) went into space, tension was created by which we had lost part of the Space Race. It put Russia ahead of America in the Space Race.

Research or propaganda. Sputnik 1 was the first artificial satellite in space.

Extreemly expensive propaganda! It was the first step by the USSR to putting a man in space.

A radio programme receiver does not need to be directly in view of the transmitter to receive programme signals. For low frequency radio waves diffraction can allow them to be received behind hills, although repeater stations are often used to improve the quality of the signals.

a weather satellite and it rotates around the Earth at the same rate and in the same direction that Earth revolves so it is always fixed over the same location.

There are many arguments and one of them is ABOUT THIS

"An Indian lawyer has filed a suit against Google Earth, claiming terrorists used it to plan last month's attack on Mumbai and demanding that it block satellite images of sensitive places in the country."

Either Some ones TV stops working or America will Nuke China because they think the shot down their satellite. Whatever happens it will result in the end of the world, one way by radiation, the other by boredom.

No. No spacecraft has gone past Eris, nor are there currently plans to send anything there.

A geostationary orbit is an orbit of the Earth that is circular, over the equator,

and at the right distance to have a period of 24 hours. A satellite in such an orbit

appears to hang motionless, always at the same point in the sky

Anything else is a non-geostationary orbit. A satellite in one of those appears to move

in the sky, so that if you want to communicate with it, you need a movable dish.

The Voyager 1 was a space probe that was launched by NASA on September 5th, 1977 with the intention of studying the outer Solar System and interstellar medium. Currently, it is still operating and regularly sends back data to the Deep Space Network.

frequency modulation, preferably.

Many countries have the ability to produce satellites: China, India, Japan, Germany, France, Canada, the United States, and Russia. A smaller number of countries have facilities for launching satellites.

Rakesh Sharma has been granted several patents for his inventions. Some of these inventions are: Profiling Stored Procedures, Distributed Overlay Network Data Traffic Management by a Virtual Server and Remote Direct Memory Access Socket Aggregation.

You would usually find a satellite up in space, and at places like ESA, JEXA, and NASA

Note that the term "satellite" does not just refer to artificial satellites. The moon is a satellite because it orbits the Earth. Any of the moons of the various planets are satellites of those planets. The Earth (and the other planets) are all satellites of the Sun.

A satellite is any body which is attached to another body via gravitational pull.

Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
