What is the main characteristic of a geostationary satellite's footprint?
its location
What type of satellite is geostationary operational environment satellite how does it work?
a weather satellite and it rotates around the Earth at the same rate and in the same direction that Earth revolves so it is always fixed over the same location.
Why is geostationary important?
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). At this altitude, one orbit takes 24 hours, the same length of time as the earth requires to rotate once on its axis. The term geostationary comes from the fact that such a satellite appears nearly stationary in the sky as seen by a ground-based observer. In other words a satellite that orbits a specific part of the earth while the earth is rotating so it looks like the satellite doesn't move. For example if you put a satellite over over the geographic US it will stay over the US and turn with the earth around the axis without ever loosing site of the US.
What is the Round Trip time of a RF signal for GEO satellites?
the speed of light = 299792458 m / sGEO (Geostationary Earth Orbit) = 35863000 m above the Earth's surfaceround trip time = 2*(35863000)/299792458 =0.239 sthe time needed for an RF signal to reach a GEO satellite and gets retransmitted back to a ground station on earth is approximately 240 milliseconds(assuming zero signal propagation/processing time in the satellite and equatorial ground station location with the same longitude as the satellite slot)
What are essential conditions for a geostationary satellite?
A geostationary satellite has to be orbiting Earth in the equatorial plane, but travelling at the same speed as the Earth's rotation, so that it is constantly over the same spot on Earth. They have to stay at a fixed height, about 36,00 kilometres or 22,000 miles above the earth. They can directly communicate with a station on Earth, which can aim it's communications, through antennae, directly at the satellite, without having to adjust the antennae.

a weather satellite and it rotates around the Earth at the same rate and in the same direction that Earth revolves so it is always fixed over the same location.
What is a satellite that stays in one location is called?
No satellites stays exactly still as they could not remain in orbit, but probably you are meaning a geostationary satellite. The orbit of these satellites matches the speed of the earth turning underneath them, so they remain above the same geographical point on the earth.
What are the main features of geostationary orbits?
In the geostationary orbits, the angular speed of the satellite will be the same as that of the earth. Hence the satellite will be at the same location above our head all the time, if it is installed so. If three such geostationary satellites each above Atlantic, Pacific and Indian Ocean inclined at angle 120 degree from one another are installed, then the whole world will be connected round the clock from nook and corner.
How does the geostationary operational environmental satellite work?
it revolves around Earth at the same rate that Earth is rotating so that it is always fixed over the same location
Which direction does a direct tv satellite need to point?
Open a web browser such as Firefox and go to http://www.sat-direction.com/. Enter your address or location, and select the desired satellite. It will draw the direction of the satellite on google maps.
What is meant by a geostationary orbit and what is it used for?
A satellite in a geostationary orbit goes around the earth at the same angular speed that the earth spins on its axis. So to someone on the earth the satellite looks like its not moving because its always at the same location above the earth. These satellites are used for communication purposes. For example, TV stations can reflect their signal off of such a satellite by aiming their transmitter at it. They don't have to change their aim because the satellite is always there. Satellite dish receivers can easily pick up the reflected signal just by aiming the dish antenna at the satellite and again you don't have to change this aim because the satellite is always there. The satellites have to be in a circular orbit above the equator in order for it to be put in a geostationary orbit.

Why is a satellite in Geostationary orbit convenient for ground-space-ground relay procedures?
A satellite in a geostationary orbit stays fixed over one location on Earth, making it ideal for continuous communication and relay procedures between ground stations. This eliminates the need for tracking and pointing mechanisms, ensuring a stable connection for extended periods. Additionally, the high altitude of geostationary orbit allows for wide coverage, enabling communication over a large area.
What is a satellite that stay in the same location in the sky?
Well, darling, that would be a geostationary satellite. It hangs out 22,236 miles above the Earth's equator, matching the planet's rotation so it looks like it's just chilling in one spot. It's like the lazy Susan of satellites, always in the same place, never missing a beat.
Satellite 58 west location?
Intelsat 9 is in geostationary orbit 35,794km above the equator at orbital location 58 West (58 degrees west longitude). On the Earth's surface, this is above a mountainous rainforest in northern Brazil, about 400km NNE of Manaus, Brazil, and about 150km south of the Guyana border.
Does a satellite need fuel to keep moving?
Yes, a satellite in orbit requires fuel to make adjustments to its trajectory or maintain its position. However, satellites in geostationary orbit can maintain their position without fuel because they orbit above the same location on Earth.
