How far are satelittes from earth?
The altitude of a satellite's orbit depends on the purpose of the satellite. Photographic satellites orbit close to the Earth, to get a good view. They are about 130 miles up. We want weather satellites and communications satellites to stay in the same spot in the sky all the time, which is called "geo-synchronous orbit", 23,500 miles up. GPS satellites are about 12,000 miles up.
What layer of the atmosphere do GPS satellites orbit in?
SatellitesSatellites orbit in outer space, not in the earth. They are sent to outer space where the gravitational pull of the earth pulls them around, just as the earth is pulled around the sun in a similar manner. The layer is the exosphere. It greatly depends on what the satellite is for and who owns it how far up it orbits. Imaging satellites need to be close to the Earth, so they orbit about 130 miles up. Communications satellites are generally at 23,000 miles up. GPS satellites are up about 13,000 miles.
How long does it take a satellite to circle the Earth?
That depends on the altitude. Low altitude satellites, about 140 miles up, take about 90 minutes to orbit. Communications satellites 23,000 miles up take 24 hours. The higher the orbit, the longer it takes.
What happens to the old satellites?
Old satellites either remain in orbit as space debris, eventually falling back to Earth and burning up in the atmosphere, or are intentionally deorbited and moved to a "graveyard" orbit to reduce the risk of collision with operational satellites. Some may also be repositioned for alternative uses or repurposed for different missions.
Is the layer of the atmosphere where satellites and the space shuttle orbit the earth?
Satellites and the space shuttle orbit in the thermosphere, a layer of the Earth's atmosphere located between the mesosphere and exosphere. Temperatures in the thermosphere can reach up to 2,500°C due to the absorption of solar radiation.
How do satellites stay up in space?
Satellites stay up in space due to how fast they are traveling. If an object is in motion around a planet at the correct speed it will orbit it without crashing towards the planet.
What happened to sputnik after orbiting earth?
Sputnik was a family name for a series of satellites, most of which burned up during reentry after some time in orbit.
Why are satellites high up above the earth?
Because satellites can't stay in orbit if they're moving through air, so they have to be high enough where there's no air.
How far up in the sky are satellites?
There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level. There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level. On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.
What happens to satellites that run out of power or just reach the limit of their usefulness?
They just continue orbiting until they naturally de-orbit. Right now there's no organized effort to clean them up or purposefully de-orbit then, so they keep going until the orbit decays.
In what region of the Earth's atmosphere do Low Earth Orbit (LEO) satellites fly?
Anything up to 2000 km (1240 miles) above sea level. Low earth orbiting satellites can suffer from atmospheric drag at very low altitudes, although there is little gas around at their orbit, there may still be enough to slow the satellite and cause it's orbit to decay. The lowest satellites would be around 300km in altitude, but would not be able to sustain orbit without an occasional boost.
How many satellite stay in orbit?
Precise numbers of "spy satellites" are unavailable, and constantly changing. Dozens, certainly. There are several different types of "spy satellites". There are photographic reconnaissance satellites, designed to take detailed photos of the surface. There are electronic surveillance satellites, designed to capture and record electronic signals such as radios.
How many miles up do picosat satellites orbit?
a lot
How can two orbiting satellites be joined?
the same way rockets, space shuttles and space stations join up. travel in the same direction, same orbit, similar speed and slowly approach each other
What are the 2 orbits of satellites?
Artificial and natural satellites. Artificial satellites are man-made satellites sent into space for a variety of different purposes e.g. taking pictures of the earth for scientific investigation Natural satellites are moons, which orbit planets and are not man-made.
What does orbiting satellites that send radio signals to a receiver on Earth make up?
GPS system
Do satellites us on earth orbit anything?
NO! they just are up there floating around they are not large enough to have an orbit.
