What Is A Geostationary Satellite And What Is It Used For?

A worldwide network of operational geostationary meteorological satellites is used to provide visible and infrared images of Earth’s surface and atmosphere for weather observation, oceanography, and atmospheric tracking.

What is geostationary satellite and its uses?

Geostationary satellite examples

Geosynchronous satellites are typically used for various purposes, such as communicating back and forth with spacecraft (like the Hubble Space Telescope and space shuttles), voice communication, Internet, broadcasting cable TV and radio signals, as well as weather forecasting.

How does a geostationary satellite work?

A Geosynchonous Orbit (GEO) takes a satellite around the Earth at a rate of once per day, keeping it roughly in the same area over the ground. The “stationary” part of geostationary describes how a satellite in this orbit remains fixed with respect to an observer on the ground.

What is a geostationary orbit used for?

A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth’s rotation. Located at 22,236 miles (35,786 kilometers) above Earth’s equator, this position is a valuable spot for monitoring weather, communications and surveillance.

What do you mean by geostationary satellite?

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). BGAN, the new global mobile communications network, uses geostationary satellites.

What are 3 uses of satellites?

Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and space telescopes. Space stations and human spacecraft in orbit are also satellites.

What is the most important application of geostationary satellite?

The first and still, arguably, most important application for communication satellites is in international telephony. Fixed-point telephones relay calls to an earth station, where they are then transmitted to a geostationary satellite.

What are the uses of geostationary and polar satellites?

Polar orbits are often used for earth-mapping, earth observation, capturing the earth as time passes from one point, reconnaissance satellites, as well as for some weather satellites. The Iridium satellite constellation also uses a polar orbit to provide telecommunications services.

How does a satellite stay in geostationary orbit?

So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits. The higher the orbit, the less velocity is required.

What is the difference between geostationary and geosynchronous satellite?

While geosynchronous satellites can have any inclination, the key difference to geostationary orbit is the fact that they lie on the same plane as the equator. Geostationary orbits fall in the same category as geosynchronous orbits, but it’s parked over the equator.

Can you see a geostationary satellite?

The GOES geostationary satellites are about 22,300 miles above Earth’s Equator and require a telescope to see, but you may be able to see a polar orbiting satellite (orbiting about 500 miles about Earth’s surface) with just a pair of binoculars or, if it’s dark enough, just your eyes!

What are the characteristics of geostationary satellite?

Characteristics of geostationary satellite. Surface insolation is one of the major indicators for climate research over the Earth system. For the climate research, long-term data and wide range of spatial coverage from the data observed by two or more of satellites of the same orbit are needed.

What is the period of a geostationary satellite?

Geostationary orbit. Geostationary orbit, a circular orbit 35,785 km (22,236 miles) above Earth’s Equator in which a satellite’s orbital period is equal to Earth’s rotation period of 23 hours and 56 minutes. A spacecraft in this orbit appears to an observer on Earth to be stationary in the sky.
