What is orbit and its types?
There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface.
How many different types of orbits are there?
There are two types of orbits: closed (periodic) orbits, and open (escape) orbits. Circular and elliptical orbits are closed.
What are orbits in remote sensing?
Satellites have several unique characteristics which make them particularly useful for remote sensing of the Earth’s surface. The path followed by a satellite is referred to as its orbit. Satellite orbits are matched to the capability and objective of the sensor(s) they carry.
What is the difference between GSLV and PSLV?
Difference between PSLV and GSLV PSLV is designed mainly to deliver earth observation or remote sensing satellites, whereas, GSLV has been designed for launching communication satellites. GSLV delivers satellites into a higher elliptical orbit, Geosynchronous Transfer Orbit (GTO) and Geosynchronous Earth Orbit (GEO).
What is an orbit for Class 3?
An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth (or) the moon (or) like some other planets also.
What are the two main types of satellites?
There are two different types of satellites – natural and man-made. Examples of natural satellites are the Earth and Moon. The Earth rotates around the Sun and the Moon rotates around the Earth. A man-made satellite is a machine that is launched into space and orbits around a body in space.
What are the two types of orbits for satellites?
Artificial satellites travel in one of two different orbits:
- polar orbits.
- geostationary orbits.
What type of orbit is ISS in?
Earth orbit
SATCAT no. The International Space Station (ISS) is a modular space station (habitable artificial satellite) in low Earth orbit.
What is an eye orbit?
The orbit is the bony cavity in the skull that houses the globe of the eye (eyeball), the muscles that move the eye (the extraocular muscles), the lacrimal gland, and the blood vessels and nerves required to supply these structures.
What are polar orbits used for?
Satellites with polar orbits are used for monitoring the weather, military applications (spying) and taking images of Earth’s surface. Geostationary satellites take 24 hours to orbit the Earth, so the satellite appears to remain in the same part of the sky when viewed from the ground.
Which one is better PSLV or GSLV?
GSLV has the capability to put a heavier payload in the orbit than the Polar Satellite Launch Vehicle (PSLV). PSLV can carry satellites up to a total weight of 2000 kg into space and reach up to an altitude of 600-900 km. GSLV can carry weight up to 5,000 kg and reach up to 36,000 km.
