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.
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.

How do geosynchronized satellites work?
An awesome question. Satellites that are stationary, compared to our planet, are moving at at exactly the same speed as our planet's rotation. To do this, a satellite must be exactly a certain distance away from our planet so it "falls" at just the right speed as to never change it's apparent position. That distance is 35,786 kilometers (give or take a few meters).
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.
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 type of satellite orbits the earth at 22300 miles above the earth?
A satellite in a geostationary orbit orbits the Earth at around 22,300 miles above the equator. Geostationary satellites appear to be stationary in the sky relative to a fixed point on the Earth's surface, making them ideal for communication and weather monitoring.
What is the significance of the geo orbit radius in relation to satellite communication?
The geo orbit radius is significant in satellite communication because it determines the satellite's position relative to the Earth. Satellites in geostationary orbit, which have a radius of about 22,236 miles, appear stationary from the Earth's surface. This allows for continuous communication with fixed ground stations, making them ideal for services like television broadcasting and weather monitoring.
What is path satellite takes around earth?
Satellites typically orbit Earth in elliptical or circular paths. The specific path depends on the satellite's purpose and altitude. Low Earth orbit satellites circle the Earth more quickly, while geostationary satellites orbit at the same rate as the Earth's rotation, appearing to stay stationary in the sky.
What force allows satellites to orbit the earth?
Gravity is the force that allows satellites to orbit the Earth. The gravitational pull between the Earth and the satellite causes the satellite to continuously fall towards the Earth while moving forward at a speed that keeps it in orbit.
Geosynchronous satellites above the equator do what?
Geosynchronous satellites ('stationary' ones that is) are usually 36 000 km above the Equator, and thus appear to be fixed relative to a given location on earth. They are comm satellites, but because of the distance, the return trip for a signal to them is about 1/4 second. This delay causes trouble with phone comms. You must have been annoyed by those attempts at 'live' TV interviews via such a system. However, for latitudes above say 55o, the sight path to the satellite becomes closer to to horizontal at that site, and may be blocked by buildings, mountains, etc. To service these latitudes, geostationary satellites are positioned to have their rotation plane inclined to the equator. This improves their performance for comms, but at the expense of them no longer appearing to be stationary in the sky.
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.
