how is an artificial satellite set on an orbit around the earth?

As DaveC mentioned a rocket is used to 1) lift a satellite radially in the gravitational field, and 2) increase it's azimuthal (centrifugal) velocity. The energy and angular momentum of the satellited at the end of the launch trajectory has to match orbital parameters at some tanget to the desired orbit. A satellite can be maneuvered with thrusters, but bascially, it is a matter of achieving the right orbital parameters for given orbit.aqua_s said:how is an artificial satellite set on an orbit around the earth?
The purpose of positioning an artificial satellite is to ensure that it is in the correct orbit to fulfill its intended function. This could include communication, navigation, Earth observation, or scientific research.
The position of an artificial satellite is determined using various tracking and monitoring systems, including ground-based radar, GPS, and onboard sensors. These systems provide real-time data on the satellite's location, velocity, and altitude.
Accurately positioning an artificial satellite is crucial for its proper functioning and longevity. If the satellite is not in the correct orbit, it may not be able to communicate with Earth or gather accurate data. Improper positioning can also lead to collisions with other objects in space.
The positioning of an artificial satellite can be affected by various factors, including Earth's gravity, atmospheric drag, solar radiation pressure, and gravitational forces from other objects in space. These factors must be taken into account when determining the satellite's orbit and trajectory.
Yes, an artificial satellite's position can be adjusted through a process called orbital maneuvering. This involves using thrusters or other propulsion systems to change the satellite's velocity and alter its orbit. This is often necessary to maintain the satellite's position or to move it to a new orbit for a different mission.
