What is the name of the orbit that allows satellites to orbit the earth but yet appear stationary?

The Earth orbit in which satellites appear to be stationary is called the, "Geostationary Orbit". Some call it a synchronous orbit.

How does satellites avoid collision?
The vast majority of satellites are in geo-stationary orbits. This means, they travel around the Earth at the same speed that the Earth rotates - making them appear in the same place. One example is the GPS satellite network. Other satellites that actually orbit around the Earth, are at a different altitude - so they would (thoretically) never collide with a stationary one. Those that are orbiting, are placed in such a way, that they also avoid each other.
What are various satellite sub-systems?
how a satellite can appear to be stationary above the earth´s surface how a satellite can appear to be stationary above the earth´s surface
What are the different artificial satellites launched into orbit?
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
What force allows satellites to orbit the earth?
Gravitational
What is a non Geo stationary satellite?
Non Geo stationary satellite is that satellite which has different angular velocity from earth and not placed on the height of 36000 Km from the earth. If you use Geo stationary satellite than only 3 satellites are enough to cover whole world. most of satellite are geostationary and they are(most of them) active satellites too.
What are Geo - stationary orbit satellites?
Geo stationary satellites are man made objects sent up into space that orbit the Earth parallel with and in the plane of the equator. They are sent up into space so that their distance from the Earth and hence their orbital speed matches the speed with which the Earth rotates on its axis. This means that they maintain a constant "stationary" position over a point on the equator of the planet. This is useful for communications and earth observation purposes.
Why do all satellites face south?
This allows them to see the entire surface of the Earth. The Earth is rotating East to West. (Or West to East if you were the satellite.) If you placed a satellite into an East-West orbit, it would not see the polar regions. If it were high enough (geo-stationary), it would only see one spot on the Earth. By using North-South (polar) orbits, the satellites will, after several orbits, be able to see the entire surface of the Earth.
How many times does a GPS satellite orbit the earth in a week?
The GPS satellites are not in geo-stationary orbit, but instead orbit twice every time the Earth rotates once. This means that for any observer the satellites appear to orbit once overhead each day. Such an arrangement gives better coverage. It is also clever in the sense that the motion of any GPS satellite will repeat itself each day. The GPS constellation of 24 satellites are arranged in six different orbital planes, each inclined 55 degrees to the equator. To obtain exactly two orbits per day, the satellites are placed at an altitude of 20,200km!!!
Is any kind of satellite stationary in the night sky?
Yes. There are many satellites that are geostationary. That is they remain fixed over the same relative position of the Earth. In the night sky, it would appear to not move in relation to the background stars and other stellar bodies.
Why overhead stars do not twinkle?
Stars are not twinkling really. It is because of the atmosphere of the earth due to which they appear twinkling. However if they are seen from above the atmosphere of earth then they appear stationary.
What is meant by the term bgan?
The term BGAN means Broadband Global Area Network. It is made up of three satellites which is owned by Inmarsat. You can connect with the satellites using any of the BGAN terminals because the satellites are in stationary orbit around the earth.
How far must a geostationary communication satellite orbit?
Geo-stationary communication satellites are 35,768 Km far from earth surface at an equatorial latitiude.
