In this modern time, we could not put a single step without any help of a satellite but we don't know properly how it is helping us in every nanoseconds. Enjoying the world cup sitting at your drawing but never think how the photo coming to you, through the space or the ocean.
How many types of satellites are there?
Parts of a satellite?
The size and shape of satellites vary widely. However, the majority share at least two components, namely an antenna and a power source. Information is frequently sent and received from and back to Earth through the antenna. A solar panel or battery may be used as the power source. Solar panels generate electricity by converting sunlight.
Cameras and scientific sensors are found on several NASA satellites. These devices may occasionally point toward Earth in order to collect data regarding its atmosphere, oceans, and land. Sometimes they look up into space to gather information about the solar system and cosmos.
How do satellites orbit the earth?
How do engineers keep satellites in the orbit around the earth?
The Rockets are used to put the majority of satellites into orbit. When the pull of Earth's gravity and the satellite's speed are equal, the satellite circled the earth.
Without this equilibrium, the satellite would either fall back to Earth or shoot off into space in a straight path. Satellites orbit Earth at different heights, different speeds and along different paths.
How many types of satellite orbits are there?
The two most common types of orbit are "geostationary" and "polar".
A geostationary satellite moves from west to east over the equator. It rotates at the same speed and in the same direction as Earth. A geostationary satellite seems to be stationary from Earth because it is always above the same spot.
Polar orbiting satellites move from pole to pole in a north-south orientation. These satellites can scan the entire planet, while Earth spins under them, one strip at a time.
