Explain Different Types of Satellite Orbits

Satellite orbits are classified as high and low orbits polar orbits when the orbital plane contains the spin axis of the earth equatorial orbits orbital plane coincides with the equatorial plane of the earth and pro-grade and retro-grade or bits the direction of satellite motion is either eastward or westward. This orbit is ideal for certain kinds of communication satellites or meteorological weather satellites that have a job to do over one part of the world.

Types of Satellite Orbits The figure below represents the circular orbital shape of the satellite.

. MEO Medium Earth Orbit 2000km up to Geosync. 160km to 2000km altitude. MEO Medium Earth Orbit or ICO Intermediate.

Geosynchronous geostationary satellites orbit 36000 km over the equator and remain over a single spot. Circular orbits comprises of geostationary polar sun-synchronous and equatorial orbits. Types of Satellite Systems Four different types of satellite orbits have been identified depending on the shape and diameter of each orbit.

Heres a list of various types of orbits. Unlike a single satellite a constellation can provide permanent global or near-global coverage such that at any time everywhere on Earth at least one satellite is visibleSatellites are typically placed in sets of complementary orbital planes and connect to globally distributed ground stations. It flies at an altitude ofRead More.

LEO Low Earth Orbit at 500-1500 kms above earths surface. When it does it is called geostationary. Polar orbits are useful for spacecraft that carry out mapping or surveillance operations.

The High Earth orbit satellite is the only non-circular orbit of the four types. We offer plenty of online educational resources on various subjects with proper definitions solved examples and other cool stuff. LEOs will orbit at a distance of 500 to 1000 miles above the earths surface.

Those are little LEOs big LEOs and Mega-LEOs. They cannot cover the high latitudes. For educators teachers and parents your.

GEO Geostationary Earth Orbit at 36000 kms above earths surface. Video showing the difference between a geostationary orbit and a polar orbit. A number of scientific satellites such as ESAs Cluster and XMM-Newton follow very elliptical egg-shaped orbits that bring them close to.

Types of satellite orbits and their features UPSC IAS About Geostationary Orbit GEO UPSC IAS. HEO satellite operates with an elliptical orbit with a maximum altitude apogee similar to GEO and a minimum altitude perigee similar to the LEO. We will take a look at all of the orbits mentioned above and understand the purpose they serve due to their unique vantage.

Features of Geostationary Orbits. The orbit is in equatorial plane ie. Often a satellite in geosynchronous orbit stays above the same spot on Earth.

In orbital mechanics a transfer orbit is an intermediate elliptical orbit that is used to move a spacecraft from one circular or largely circular orbit to another. There are several types of transfer orbits which vary in their energy efficiency and speed of transfer. Directly above the equator and thus inclination.

Types of Satellite Orbits. Though no orbit is perfectly circular the general name for any orbit that is not highly elliptical is circular. As it is clear from the above figure that the radius of the elliptical orbit is variable but that of a circular orbit is constant.

Based on the distance from Earth the types of orbits are classified into low earth orbit medium earth orbit the geostationary orbit and high earth orbitEach of these orbits serves specific applications concerning coverage area cost and purpose. A satellite constellation is a group of artificial satellites working together as a system. Majorly there are two major divisions in orbit types.

Also the elliptical satellite orbit is given as. The satellites orbit is a critical component of its function. The yellow areas shows what part of Earth each satellite sees during its orbit.

Basically there are 3 kinds of satellite orbits which depend on its position relative to the surface of the Earth. 63 of current operational satellites are at a low orbit level 2000 Km 6 are at medium orbit level 20000 km 20 are at the geostationary orbit level 36000 km and the rest 2 at elliptic level 36000 km. Geostationary orbitA satellite on a geostationary or geosynchronous orbit stays in the same spot relative to Earth.

LEO Low Earth Orbit. Circular orbits and elliptical orbits. The HEO satellites used for the special applications where coverage of high latitude locations is required.

Hohmann transfer orbit an elliptical orbit used to transfer a spacecraft between two circular. Remote sensing satellites use two types of orbits. These satellites are used for satellite phones and GPS.

Depending on your source the defined upper limit for LEO varies wildly from 200km clear up to geosync. A geostationary orbit also referred to as a geosynchronous equatorial. These satellites are placed in Space at different altitudes and they are facing different planets depending on the applications.

Answer 1 of 4. They always view the same region and produce the movie loops seen on TV news. Some satellites including the International Space Station follow low orbits that are inclined tilted to the equator.

Low Earth Orbit Satellites. Satellites have different orbits because their orbits depend on what each satellite is designed to accomplish. Low Earth Orbit LEO satellites are mainly classified into three categories.

Ten or more MEO satellites are required in order to cover entire earth. Types of Orbits for UPSC GEO Geostationary Earth Orbit Low Earth Orbit LEO Medium Earth Orbit MEO Polar Orbit Sun-Synchronous Orbit SSO Geostationary Transfer Orbit GTO.
