Which of the following is an advantage of LEO satellites Internet over GEO satellite Internet?

Comparing to traditional geostationary earth orbit (GEO) systems, LEO satellite constellation takes advantages of low propagation delay, small propagation loss and global coverage.

Is a space tether possible?

Researchers are still looking into what materials would make the best space tethers. In fact, one possibility is based on fishing line! The tether will have to be able to resist the corrosion caused by atomic oxygen in the upper reaches of Earth’s atmosphere, as well as damage from micrometeoroids.

Why are geostationary satellites above the equator?

It is always directly over the same place on the Earth’s surface. Satellites in geostationary orbit rotate with the Earth directly above the equator, continuously staying above the same spot. This position allows satellites to observe weather and other phenomena that vary on short timescales.

What are disadvantages of LEO?

Following are the disadvantages of LEO orbit: ➨As it is at lesser distance above the Earth, it covers less region of the earth. Hence large number of satellites are needed to cover the entire region of the Earth. ➨Ground station is very complex as it requires to handle frequent handoffs between LEO satellites.

Can a building reach space?

A tower that could reach space would be too heavy for the Earth to support, he says. Earth’s crust isn’t very deep. It averages only around 30 kilometers (17 miles). The tower’s mass would push too hard on the Earth’s surface.

Is China building a space elevator?

China Shoots for Stars With Plans to Build Space Elevator by 2045. (Yicai Global) Nov. 17 — The China Academy of Launch Vehicle Technology, a subordinate of the nation’s main space program contractor China Aerospace Science and Technology Corp. By 2035, CASC hopes to make all of its launch vehicles reusable.

Can a satellite be stationary?

All geostationary satellites are geosynchronous. The “stationary” part of geostationary describes how a satellite in this orbit remains fixed with respect to an observer on the ground. This is an ideal orbit for communications satellites, since ground-based antennas can remain pointed at the same spot in the sky.

What are LEO satellites used for?

Most of the LEO satellites are used for Earth or space observation and science. The best examples of LEO satellites are the Hubble space telescope, the Spot family of satellites (Earth imaging and survey) and military observation satellites.

What is an LEO satellite?

LEO – Low Earth Orbit One of the hot topics right now is the race to establish a network of Low Earth Orbit satellites. LEO satellites occupy the lowest orbit of all satellite types, often between 800 – 1,600 km (500 – 1,000 miles) above the surface.

What is a low Earth orbit satellite?

One of the hot topics right now is the race to establish a network of Low Earth Orbit satellites. LEO satellites occupy the lowest orbit of all satellite types, often between 800 – 1,600 km (500 – 1,000 miles) above the surface.

What is the difference between Leo and Geosynchronous satellites?

As compared to geosynchronous orbiting satellites at 36,000 km, LEO travel through a much denser atmosphere and thus experience far more aerodynamic drag. This means they require more power to travel at higher speeds and make corrections to maintain their lower orbits.

What is the difference between GEO and Leo?

These satellites are fixed at a position on the GEO belt moving with the Earth as it rotates. It is positioned at a very large distance from the Earth (must larger than LEO). Because of this, the satellite can cover larger areas of land mass and bodies of water.
