What else can I help you with?
Where do you think Earth-observing satellites orbit and what determines their orbital altitude?
Earth-observing satellites typically orbit in low Earth orbit (LEO) or geostationary orbit (GEO). The orbital altitude of these satellites is determined by factors such as the mission objectives, desired coverage area, and the balance between gravitational pull and orbital velocity.
Is the moon in a geostationary orbit about the earth?
No. A satellite in geostationary orbit remains stationary over a single point on the earth's equator. It must have an altitude of 22,236 miles above the earth, which makes its orbital period exactly one day. The moon is much too far away for that; its orbital period is 28 earth days.
What is the radius of a geostationary orbit around Earth?
The radius of a geostationary orbit around Earth is approximately 42,164 kilometers.
The factors which make a geostationary orbit?
-- circular orbit, rather than elliptical -- orbit positioned over the equator, not inclined to it -- correct orbital radius to result in a period equal to the sidereal day = approx 23hr 56min
What is the definition of a geostation?
A geostationary orbit is a circular orbit above the Earth's equator at an altitude where the orbital period matches the rotation period of the Earth. This results in the satellite appearing stationary relative to a fixed point on the Earth's surface. Geostationary satellites are commonly used for telecommunications, weather monitoring, and broadcasting.
Which is closer to the sun a satellite in Leo orbit or in geostationary orbit?
LEO orbit is closer to the Earth than a geostationary orbit is.There's essentially no difference in their distance from the Sun.
Why a precise geo stationary orbit can not be obtained?
Because the geostationary orbit round the Earth is perturbed by gravity from the Sun and Moon. The biggest effect is to change the orbital plane of the geostationary satellite so that, after a while on station, in 24 hours it appears to move up and down slightly. For that reason communications satellites need motors and fuel to correct the orbit from time to time.
Are geostationary orbit and equatorial orbit same?
No. Geostationary orbits are equatorial, but equatorial orbits are not necessarily geostationary. To be geostationary, the orbit needs to be equatorial, circular and at the altitude such that one orbit takes one sidereal day (approximately 24 hours 3 minutes 56 seconds. ) An equatorial orbit need only be located above the equator, may have any period and need not be circular.
How are satellites stationed?
The time for one (stable) orbit is directly linked to the orbital radius. At one particular radius (geostationary), the resultant stable orbit velocity is exactly enough to match the rotation of the earth, keeping the satellite overhead at all times. This geostationary radius is approximately 42 000 km from earths centre and most geostationary satellites are roughly in the equatorial plane.

How can you tell if a satellite is in a geostationary orbit?
me nuh care
How can you tell a satellite is in geostationary orbit?
A satellite is in geostationary orbit when it orbits the Earth at the same speed and direction as the Earth's rotation. This allows the satellite to appear stationary from the surface of the Earth. Measurements of its position and velocity can confirm that it is in geostationary orbit.
