well u know earth have some gravitational force
actually theres always some gravitational force in each and every thing that exist
so warth have a good gravitational force
so its extended to many kilometers
as you go far from earth its gravitational force decrease
then at a point of time its gravitational force become so less that it just holds the object in its place i mean its neither too much gravitational pull there but only the amount that anything is in that place stays there itself and this place or this particular place is known as orbit where anything is bounded towards something and where it cam move around that thing
u can see the example of moon
its at such a place that it experiencs the pull of earth but still it doesnt not fall into the earth because the pull is not so strong that it pull moon towards itself
the streangth of pull is just enought that it keps the think or sam moon bounded to itself
so what happenes is this that a satellite is made up
its loaded on a rocket as each rocket have some capacity to carry certain amount of load with itself commonly know as payload capacity
it carried the satellite to that place called orbit
it unloads the satellite there in the orbit
and each satellite have requires some fule to work and orbit around the earth
and that energy it takes from sun or say the solat eberdy thats y u might have seen so huge solar cell panels on any satellite.
and after the satellite is successfully places in the orbit and it starts working the space shuttle returns back to earth.

All satellites today get into orbit by riding on a rocket or by riding in the cargo bay of the Space Shuttle. Several countries and businesses have rocket launch capabilities, and satellites as large as several tons make it safely into orbit on a regular basis.
For most satellite launches, the scheduled launch rocket is aimed straight up at first. This gets the rocket through the thickest part of the atmosphere most quickly and best minimizes fuel consumption.
After a rocket launches straight up, the rocket control mechanism uses the inertial guidance system to calculate necessary adjustments to the rocket's nozzles to tilt the rocket to the course described in the flight plan. In most cases, the flight plan calls for the rocket to head east because Earth rotates to the east, giving the launch vehicle a free boost. The strength of this boost depends on the rotational velocity of Earth at the launch location. The boost is greatest at the equator, where the distance around Earth is greatest and so rotation is fastest.

An addendum to Billruss's wonderful reaction: In area each thing will stay nevertheless besides except acted upon with the help of a stress - as Newton stated - so truly the question is- how does a satellite tv for pc take care of to bypass on an analogous cost the earth does? The gravity of earth will pull and merchandise down- and in view that the warping of area - it is what gravity is idea to be - is a curve - a satellite tv for pc is resembling a marble rolling around the authentic of a (close to frictionless) bowl - for this reason as quickly by using the undeniable fact that's put in orbit - it truly is going to like as no longer stay there advert infinitum - yet honestly loses a niche of momentum and finally decays - that is why often times they fall back to earth - and want replacing.

a multistaged rocket is used to launch satellites in space. 1st rocket will take the satellite to a desired height and the 1st rocket goes off. with the help of boosters the rocket is tilted with 90 deg.
2nd rocket will impart the reqd. critical velocity so that it can utilize the earth's grav force as centripetal force and perform circular motion around the earth.

the rocket in which the satellite is being sent moves at such a speed that it reaches the escape velocity of earth and then the satellite is launched from the rocket at the speed of the orbital velocity of the earth and then the satellite stays in the orbit around the earth.

Some are delivered by the space shuttles. Some are fired into orbit atop atlas rockets.

They are placed in orbit by rockets, small trips only to put the satellite in orbit..

It is attached to a rocket and rocket escapes earths gravity and once it reaches its calculated orbit it releases the satellite
