What are the types of satellite and their uses?
| Application Details | Solar Power Space-based satellites gather energy from the Sun and transmit it to earth for consumption. | Miniaturized Smaller sized and lower weight satellites are launched at an economical cost used for the limited purpose of scientific data gathering and radio relay. |

What are the 3 types of satellite communication?
There are three types of communication services that satellites provide: telecommunications, broadcasting, and data communications .
What is the most common type of satellite?
Satellites orbit Earth at different heights, different speeds and along different paths. The two most common types of orbit are “ geostationary” (jee-oh-STAY-shun-air-ee) and “polar.” A geostationary satellite travels from west to east over the equator.
What are the 4 main types of satellites?
Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites , and space telescopes.
What are two types of satellite?
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.
How do you build a satellite?
- Container: juice box.
- Power source: solar panel made from shiny book cover, construction paper, and a skewer.
- Instruments: bits of sponges.
- Communication: antenna made from a screw.
- Orientation finder:star tracker made from a washer.
- Held together with: Elmer’s glue.
What are the main satellites?
There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth). There are dozens upon dozens of natural satellites in the solar system, with almost every planet having at least one moon.

How many satellites are in space?
There are nearly 6,542 satellites orbiting the Earth as of January 1, 2021. Out of which 3,372 satellites are active, and 3,170 satellites are inactive.
What is the working principle of satellite?
The fundamental principle to be understood concerning satellites is that a satellite is a projectile. That is to say, a satellite is an object upon which the only force is gravity . Once launched into orbit, the only force governing the motion of a satellite is the force of gravity.
How can I get a satellite phone?
The ‘General Public ‘ can now buy a Satellite Phone in India. So why is government so coy about it? The ‘general public’ is invited to fill up a customer acquisition form, submit it to government telecom provider, BSN, buy a satphone from one of 7 franchisees listed and use a BSNL-supplied SIM.
Do satellites move in a straight line?
Initially, the satellites were seen to be stretched out in a straight line measuring roughly 5 to 8 degrees in apparent length. Your clenched fist held at arm’s length is roughly equivalent to 10 degrees, so the satellite train currently measures roughly just less than a fist in length as it moves across the sky.
Which country has the largest number of satellites?
Of the 3,372 active artificial satellites orbiting the Earth as of January 1, 2021, 1,897 belong to the United States . This is by far the largest number of any single country, with their nearest competitor, China, accounting for only 412.
What is the difference between geostationary and geosynchronous satellites?
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.
