The satellites that are in space are actually orbiting the earth as they are up in space.
The satellites are not just staying in one place and although some gravity from earth still pulls as the satellites they are not able to fall because of the constant orbiting of the satellite.
As long as the satellites maintain the proper speed orbiting the earth they will not be able to fall out of the sky or space.
If the satellite were to stop orbiting the earth then they would likely fall out of the sky.
The satellites that are in space are taken up into space in rockets and the reason the satellites stay in space is because of the earth which is curving away while both the rocket and the satellite “fall” around the Earth.
The satellite is able to stay in that orbit as long as the satellite in space keeps its speed to stay balanced by the headwinds.
