SATELLITE
TYPES OF SATELLITE
Low Earth Orbit
Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth.
A low Earth orbit is an orbit around Earth with a period of 128 minutes or less and an eccentricity less than 0.25.
Medium Earth Orbit
MEO satellites are commonly used for positioning information like GPS, GLONASS and Galileo. GPS satellites have an altitude of about 22000km, which gives an orbital period of 12 hours.
A medium Earth orbit is an Earth-centered orbit with an altitude above a low Earth orbit and below a high Earth orbit – between 2,000 and 35,786 km above sea level.
Geostationary Orbit
There are many geostationary satellites located over the Equator, which causes congestion of the area. To prevent signal interference, precise positioning of each satellite is ensured prior to launching.Geosynchronous satellites are often used to monitor weather events or transmit television and communications signals.
A geostationary orbit, also referred to as a geosynchronous equatorial orbit, is a circular geosynchronous orbit 35,786 km in altitude above Earth's equator, 42,164 km in radius from Earth's center, and following the direction of Earth's rotation.
Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder.

TYPES OF SATELLITE
Sputnik 1
Sputnik 1 was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program.
It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958.
Weather Satellite
Meteorological satellites can also detect other phenomena such as city lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, and energy flows.
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth.Satellites can be polar orbiting or geostationary.
Earth Observation Satellite
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation from orbit, including spy satellites.
These satellites detects the changes in the earth vegetation, ocean color, radiation from the earth surface. These satellites are also used to map the terrain.
Navigation Satellite
The navigation satellites determine the geographic location of ships, aircrafts, or any other object.
The navigation satellite system with global coverage is called Global Navigation Satellite System (GNSS).
TYPES OF SATELLITE
Bio Satellite
They are used to research the effects of space on biological matter while in orbit around a celestial body.
A bio satellite is an artificial satellite designed to carry plants or animals in outer space.
Reconnaissance Satellite
A reconnaissance satellite or intelligence satellite is an Earth observation satellite or communications satellite deployed for military or intelligence applications. A reconnaissance satellite might also be referred as spy satellite.
Reconnaissance satellites are designed to observe the Earth for military purposes. Such satellites comprise of infrared sensors that trace missiles launched and electronic sensors that eavesdrop on confidential conversations amongst other acts of military surveillance.
Geostationary Satellite
Geostationary satellites are equipped with transponders that receive, amplify and retransmit radio signals to and from Earth. These signals can be used for a wide range of applications, including telecommunications, broadcasting, remote sensing and navigation.
A geostationary satellite is an Earth-orbiting satellite placed at an altitude of approximately 22,300 miles or 35,800 kilometers directly above the equator. These satellites revolve in the same direction the Earth rotates (west to east).
An artificial body placed in orbit round the earth or moon or another planet in order to collect information or for communication.
A satellite is basically a self-contained communications system with the ability to receive signals from Earth and to retransmit those signals back with the use of a transponder-an integrated receiver and transmitter of radio signals.
