Which altitude that satellites are normally orbit around the earth?

Answer 1

Low satellites, like the space station, the Hubble space telescope and Iridium satellites, are a few hundred miles up. Geostationary satellites, like direct TV satellites, are about 22,000 miles up.

Answer 2

Satellite's swings out 22300 miles and back in to an altitude of 100 miles above Earth. At an assigned time and place.
A satellite remains in orbit because this force of gravity provides the centripetal force.

Exact speed depends on the Shuttle's orbital altitude.


There are three basic kinds of orbits, depending on the satellite's position relative to Earth's surface:
Geostationary orbits (also called geosynchronous or synchronous) are orbits in which the satellite is always positioned over the same spot on Earth. Many geostationary satellites are above a band along the equator, with an altitude of about 22,223 miles, or about a tenth of the distance to the Moon. The "satellite parking strip" area over the equator is becoming congested with several hundred television, weather and communication satellites! This congestion means each satellite must be precisely positioned to prevent its signals from interfering with an adjacent satellite's signals. Television, communications and weather satellites all use geostationary orbits. Geostationary orbits are why a DSS satellite TV dish is typically bolted in a fixed position.

The scheduled Space Shuttles use a much lower, asynchronous orbit, which means they pass overhead at different times of the day. Other satellites in asynchronous orbits average about 400 miles (644 km) in altitude.

In a polar orbit, the satellite generally flies at a low altitude and passes over the planet's poles on each revolution. The polar orbit remains fixed in space as Earth rotates inside the orbit. As a result, much of Earth passes under a satellite in a polar orbit. Because polar orbits achieve excellent coverage of the planet, they are often used for satellites that do mapping and photography.

Answer 3

Define "normal." Campbelp gave the best answer...it varies depending on the purpose of the satellite. The space shuttle is never more than a few hundred miles, while television and weather satellites are about 22,000 miles.

Answer 4

I believe the lowest orbit is 100 miles.

Answer 5

normally satellites orbit at a height of 36000km

Answer 6

...and military satellites make occasional dips down to less than (???) 100 miles to make close inspections of interesting targets.
