What is a Geostationary Satellite?
Geostationary satellites orbit the equator at the same rate the earth spins, once per day. They orbit at a distance of 35,900 km above an (almost) fixed spot above the Equator on the earth's surface.

How do Satellites get into space?
A satellite is sent into space on top of a rocket. When a satellite is put into space, we say that it is “launched.”
The rocket that is used to launch a satellite is called a “launch vehicle.” Below are pictures of some launch vehicles currently used to put satellites into space.
