Explain Different Types of Satellite Orbits

The satellite orbits at an elevation of approximately 35 831 km because that produces an orbital period time for one orbit equal to the period of rotation of. Often a satellite in geosynchronous orbit stays above the same spot on Earth.

Types Of Satellite Based On Orbits

164 Explain what GEO LEO and MEO satellites are including what the acronyms stand for.

. Low Earth Orbit LEO satellites are mainly classified into three categories. 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. Geosynchronous geostationary satellites orbit 36000 km over the equator and remain over a single spot.

The satellites are also classified based on the following types of orbits. GEO Geostationary Earth Orbit at 36000 kms above earths surface. Each of these orbits serves specific applications concerning coverage area cost and purpose.

Answer 1 of 4. MEO Medium Earth Orbit 2000km up to Geosync. A number of scientific satellites such as ESAs Cluster and XMM-Newton follow very elliptical egg-shaped orbits that bring them close to.

Satellites can operate in several different types of Earth orbit. Video showing the difference between a geostationary orbit and a polar orbit. Low Earth Orbit Satellites.

MEO Medium Earth Orbit or ICO Intermediate. LEO Low Earth Orbit. Also the elliptical satellite orbit is given as.

It flies at an altitude ofRead More. Considering the near-circular orbit e 0 it is obvious that the semi-major axis a is the most important parameter that determines satellite orbit speed and orbital periodIn general polar-orbiting satellites have 7000 km of the semi-major axis so that satellites have. The orbit is in equatorial plane ie.

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. Satellites have different orbits because their orbits depend on what each satellite is designed to accomplish. Geostationary orbitA satellite on a geostationary or geosynchronous orbit stays in the same spot relative to Earth.

Majorly there are two major divisions in orbit types. Types of satellite orbits and their features UPSC IAS About Geostationary Orbit GEO UPSC IAS. Compare the three types with respect to factors such as size and shape of orbits signal power frequency reuse propagation delay number of satellites for global coverage and handoff frequency.

Ten or more MEO satellites are required in order to cover entire earth. HEO satellite operates with an elliptical orbit with a maximum altitude apogee similar to GEO and a minimum altitude perigee similar to the LEO. A geostationary orbit is one in which the satellite is always in the same position with respect to the rotating Earth.

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 orbit. Those are little LEOs big LEOs and Mega-LEOs. Features of Geostationary Orbits.

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. The yellow areas shows what part of Earth each satellite sees during its orbit. LEOs will orbit at a distance of 500 to 1000 miles above the earths surface.

Remote sensing satellites use two types of orbits. 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. Though no orbit is perfectly circular the general name for any orbit that is not highly elliptical is circular.

These satellites are placed in Space at different altitudes and they are facing different planets depending on the applications. Circular orbits and elliptical orbits. The short time of visibility with a high elevation requires additional mechanisms for connection handover between different satellites.

163 List three different ways of classifying satellite orbits. The high number of satellites combined with the fast movements resulting in a high complexity of the whole satellite system. For educators teachers and parents your.

Circular orbits comprises of geostationary polar sun-synchronous and equatorial orbits. Basically there are 3 kinds of satellite orbits which depend on its position relative to the surface of the Earth. There are several types of transfer orbits which vary in their energy efficiency and speed of transfer.

Types of Satellite Orbits. Directly above the equator and thus inclination. A geostationary orbit also referred to as a geosynchronous equatorial.

LEO Low Earth Orbit at 500-1500 kms above earths surface. Types of Satellite Systems Four different types of satellite orbits have been identified depending on the shape and diameter of each orbit. Some satellites including the International Space Station follow low orbits that are inclined tilted to the equator.

Polar orbits are useful for spacecraft that carry out mapping or surveillance operations. Where G 3986012 km 3 sec-2 is the Earths gravitational constant and a is the semi-major axis. We will take a look at all of the orbits mentioned above and understand the purpose they.

Depending on your source the defined upper limit for LEO varies wildly from 200km clear up to geosync. These satellites are used for satellite phones and GPS. We offer plenty of online educational resources on various subjects with proper definitions solved examples and other cool stuff.

The High Earth orbit satellite is the only non-circular orbit of the four types. They always view the same region and produce the movie loops seen on TV news. 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.

The satellites orbit is a critical component of its function. 160km to 2000km altitude. When it does it is called geostationary.

Types of Satellite Orbits The figure below represents the circular orbital shape of the satellite. They cannot cover the high latitudes. Hohmann transfer orbit an elliptical orbit used to transfer a spacecraft between two circular.

The HEO satellites used for the special applications where coverage of high latitude locations is required. Heres a list of various types of orbits.
