How can you tell that a satellite is in geostationary?

Watch the satellite, with either a telescope or a very highly directional radio antenna. An observation period of twelve hours will be long enough to answer the question. If the satellite appears to move in the sky by more than a few tenths of a degree during that time, then it is not in geostationary orbit.


The time period of a geostationary satellite is?

If a satellite is in geosynchronous orbit, it will take the satellite 24 hours, a day, to orbit the Earth once. This is so because geosynchronous orbit is when a satellite orbit the Earth at such a time, that is is over the Earth at all times.


What is geosatelite?

A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time.


What is the motion of an artificial satellite?

Artificial satellites orbit the Earth. Some are geostationary - means that their orbital period matches the revolutions of the Earth, keeping them in the same spot over the surface all the time. Other travels roughly pole-to-pole, allowing them to cover the whole Earth as the Earth rotates beneath them.


Why a precise geo stationary orbit can not be obtained?

Because the geostationary orbit round the Earth is perturbed by gravity from the Sun and Moon. The biggest effect is to change the orbital plane of the geostationary satellite so that, after a while on station, in 24 hours it appears to move up and down slightly. For that reason communications satellites need motors and fuel to correct the orbit from time to time.


In what type of orbit does a satellite follow the direction of the earths rotation seeming to hover over one spot on the equator?

Synchronous orbitThis is where an orbiting body (moon) has a period equal to the average rotational period of the body being orbited (planet), and in the same direction of rotation as that body.


How are satellites stationed?

The time for one (stable) orbit is directly linked to the orbital radius. At one particular radius (geostationary), the resultant stable orbit velocity is exactly enough to match the rotation of the earth, keeping the satellite overhead at all times. This geostationary radius is approximately 42 000 km from earths centre and most geostationary satellites are roughly in the equatorial plane.


What is orbital period?

Orbital period is the time it takes a planet to go around its star once.


What satellite orbits around the earth and takes the same time it takes for the earth to rotate on its axis?

Only artificial, geostationary satellites.


What are the main features of geostationary orbits?

In the geostationary orbits, the angular speed of the satellite will be the same as that of the earth. Hence the satellite will be at the same location above our head all the time, if it is installed so. If three such geostationary satellites each above Atlantic, Pacific and Indian Ocean inclined at angle 120 degree from one another are installed, then the whole world will be connected round the clock from nook and corner.


How does the satellite transmit tv programs inspite of the fact that it moves all the time?

Answer: A geostationary satellite is any satellite which is placed in a geostationary orbit. Satellites in geostationary orbit maintain a constant position relative to the surface of the earth. Geostationary satellites do this by orbiting the earth at approximately 22,300 miles above the equator. At this altitude, the speed of a satellite's rotation around the world is identical to the rotational speed of the world itself. While the satellite is actually moving; but moving at the same speed as the rotational speed of the world itself, it is always appears in the same azimuthal (angle); latitudinal and longitudinal position of the sky over the equator. Being geostationary allows an earth receiving & transmitting station to maintain bidirectional communications with satellites without the need of having to always reposition the earth based "dish" like antenna. A practical example is one's home whose television is connected to a unidirectional (receives only) dish antenna. If the satellite that the dish antenna is aimed at was not geostationary, people would lose the satellite's signal as soon as it deviated one degree from its position. In general, all data, audio & video satellites are launched into a geostationary orbit.


Which of the planets orbital time is 7 times smaller than that of Uranus?

Jupiter's orbital period is only 1.53% less than1/7 the orbital period of Uranus.
