Satellite: Explanation and Study Guide

What is a Satellite?

A satellite is an object that orbits around a larger object. In the context of Earth science, satellites are artificial objects that are launched into space and orbit the Earth. They are used for various purposes such as communication, weather monitoring, navigation, and scientific research.

Types of Satellites

• Communication Satellites: These satellites are used for transmitting television, radio, and internet signals.
• Weather Satellites: These satellites are equipped with instruments to monitor and study Earth's weather patterns and phenomena.
• Navigation Satellites: These satellites are part of global navigation systems such as GPS, which provide precise location and time information.
• Research Satellites: These satellites are used for scientific research and exploration of space and celestial bodies.

How Satellites Orbit the Earth

Satellites orbit the Earth in various orbits, including low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary orbit (GEO). The choice of orbit depends on the specific purpose and function of the satellite.
