If altitude increases the required orbital speed of a satellite should?

For any body in a closed orbit around another body, the farther apart the two bodies are, the slower the satellite moves in its orbit.. When the Space Shuttle is in "low earth orbit", it moves faster than the Moon is moving in its orbit. A satellite in an elongated orbit, that spends some of the time close to the earth and some of the time farther away, moves fastest at its lowest altitude, and slowest when it is furthest away.

What is geosatelite?
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). A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time.
What are sun synchronous satellites?
A sun-synchronous orbit is one that places a satellite over a given location at the same mean solar time on successive orbits. This is accomplished by tuning the orbital altitude and inclination. The object is to have the same solar illumination angle at each approach, with the same orbital motion (ascending, descending). This is useful for surface observations, as with weather or spy satellites.
Why There is no work done when satellite rotate around earth?
With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 km). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth.At the correct orbital velocity, gravity exactly balances the satellite's inertia, pulling down toward Earth's center just enough to keep the path of the satellite curving like Earth's curved surface, rather than flying off in a straight line.
How long does it take to build a satellite?
The time it takes to put together a satellite varies on the size and structure of the satellite. A simple satellite could be put together in a couple of months, where a large science mission could take ten or more years.
Why does a geosynchronous satellite not trace a path over the surface of Earth?
A geostationary orbit achieved by being in a location where the satellite's orbital period is 24 hours. This means the satellite is about 36,000 km (22,000 miles) above the Earth's surface. All orbits must therefore be over the equator. Every orbit around the earth looks like a circular (or elliptical) ring whose center (or one foci) is at the center of gravity of the Earth. An orbit exactly above the equator is one such orbit, but any orbit can be tilted as long as the center (or focus) stays at the Earth's center and the whole orbit is flat like a disk. On various NASA maps this makes the orbit look like a sinewave, but on a globe it stays a flat circle (or ellipse). On "Star Trek" I have seen errors a number of times on "Geostationary orbit over the North Pole", well you can't do that. Likewise, a "Lunar-stationary orbit" is impossible for a spacecraft, since Earth itself is already IN THE STATIONARY ORBIT POSITION! Remember that a geostationary orbit looks like it is always over the same spot on the Earth (or other body). If you were on the Moon, the Earth would be in the same position in the sky at all times.
How does a satellite get into the exosphere?
It has to be carried there by a rocket, which takes it to the required altitude and orbital speed.
What is the approximate orbital altitude of a Polar Orbiting satellite?
870 km is its altitude according to NASA (answred bt divyansh tiwari)
What would be the effect on the orbital velocity of satellite if mass of satellite is double?
Its mass won't affect the orbital velocity.
What is satellite orbital spacing?
orbital spacing is the satellite spacing between the satellites orbiting in same frequency band

What does perturbation do to a satellite?
it affect the path and orbital velocity of satellite due to gravitation pull
What is a geo synchronus satellite?
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
How is orbital speed determined?
Orbital speed of a satellite: v - orbital speed G - gravitational consatnt R - radius of earth h - height of orbit
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 happens to the period as the orbital radius increases?

Does 90482 Orcus have a moon?
Yes, it has a satellite 220 km in diameter, the orbital period is still unknown. The satellite's name is Vanth.
How are the speeds and orbit times of the planets affected by it?
As it increases, the orbital speed increases, and the period (time to complete an orbit) decreases, which is why Mercury has the shortest year, and Neptune the slowest orbital speed.
