Welcome to class! 

In today’s class, we will be talking about satellite. Enjoy the class!

Satellite

Satellite is a natural body that revolves around the earth or another planet. As we have learned earlier, the earth has one satellite, which is the moon. A scientist has launched artificial satellites (like a space shuttle, rockets etc.) into space to carry out experiments, collect information and learn more about other space. A satellite is an object in space that orbits or circles around a bigger object. 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).

Types of satellite

The types of satellites include the following:

1. Communications satellites: It is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. The communication satellite is commonly used for mobile phone signals, weather tracking, or broadcasting television programs. The communication satellite is an artificial satellite that relay receive signals from an earth station and then retransmits the signal to other earth stations.
2. Weather satellites: It is a type of satellite that is primarily used to monitor the weather and climate of the Earth. Weather satellites can be polar orbiting, covering the entire Earth asynchronously, or geostationary, hovering over the same spot on the equator. The satellite can be polar orbiting, covering the entire Earth asynchronously, or geostationary, hovering over the same spot on the equator. A weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth.
3. Navigation satellites: Satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning
4. Reconnaissance satellites: It is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type took photographs, then ejected canisters of photographic film which would descend back down into Earth’s

Use of satellite

These are some of the uses of the satellite;

1. For Weather Forecasting System and tracking storms and
2. They are used for communication purpose.
3. For GPS (Global Positioning System).
4. Scientific Investigation.
