Quick Answer: What Is Meant By Meo?

What are MEO satellites used for?

MEO satellites orbit the earth at higher altitudes and therefore provide a greater coverage area to the extent that a company with 24 MEO satellites in position will have four covering any given spot on the earth at any time during the day..

What is an orbiting satellite?

An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. … Planets, comets, asteroids and other objects in the solar system orbit the sun.

What is geo MEO and LEO?

Medium earth orbit, or MEO, satellites are a bit of a middle ground between LEO and GEO orbits, circling the planet at an altitude of 8,000 miles.

What does Meo stand for in education?

Multiple Exam OpportunityThe Multiple Exam Opportunity (MEO) is a programme that was developed by the Department of Basic Education (DBE) in order to reduce stress and pressure on progressed learners for their final matric examinations.

What is the difference between LEO and GEO satellites?

Unlike GEO satellites, LEO satellites also fly at a much faster pace because of their proximity to Earth. For example, an Iridium® satellite flies at approximately 17,000 mph (completing an orbit every 100 minutes!), compared to a GEO satellite that typically flies around 7,000 mph.

What are the two types of orbits?

Types of orbitGeostationary orbit (GEO)Low Earth orbit (LEO)Medium Earth orbit (MEO)Polar orbit and Sun-synchronous orbit (SSO)Transfer orbits and geostationary transfer orbit (GTO)Lagrange points (L-points)

What is LEO system?

Short for low earth orbit, a satellite system used in telecommunications. LEO satellites orbit the earth between 400 and 1,000 miles above the earth’s surface. LEOs are mostly used for data communication such as e-mail, paging and videoconferencing.

What is the meaning of Meo?

Short for medium, or middle, earth orbit, a satellite system used in telecommunications. MEO satellites orbit the earth between 1,000 and 22,300 miles above the earth’s surface. MEOs are mainly used in geographical positioning systems and are not stationary in relation to the rotation of the earth.

What does Meo stand for in business?

Marketing Executive OfficerMEO — Marketing Executive Officer.

What keeps things in orbit?

The centripetal force keeping one object in orbit around another object is due to the gravitational pull between the two objects. … In the case of the Moon’s orbit, the centripetal force is the gravitational pull between the Moon and Earth.

How long can a satellite stay in orbit?

The satellites in the very low end of that range typically only stay up for a few weeks to a few months. They run into that friction and will basically melt, says McDowell. But at altitudes of 600 km—where the International Space Station orbits—satellites can stay up for decades.

Will all satellites eventually fall to Earth?

The Short Answer: Even when satellites are thousands of miles away, Earth’s gravity still tugs on them. Gravity–combined with the satellite’s momentum from its launch into space–cause the satellite go into orbit above Earth, instead of falling back down to the ground.

What are the three types of orbits?

There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface.

What are the types of satellite?

There are two different types of satellites – natural and man-made. Examples of natural satellites are the Earth and Moon. The Earth rotates around the Sun and the Moon rotates around the Earth. A man-made satellite is a machine that is launched into space and orbits around a body in space.

How does a satellite stay in orbit?

A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull.

What are the 3 types of satellites?

What are 3 uses of satellites?

What is a satellite give an example?

A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space.

How many satellites are in MEO?

The Global Positioning System (GPS) is a 24-satellite constellation, with each satellite in circular MEO with an altitude of about 20,000 km. The constellation is oriented such that at any given moment, every point on Earth has access to four GPS satellites.
