SATELLITE

A satellite is an object that moves around a larger object. Earth is a satellite because it moves around the sun. The moon is a satellite because it moves around Earth. Earth and the moon are called “natural” satellites. But usually when someone says “satellite,” they are talking about a “man-made” satellite.

Satellites are artificial objects placed into orbit around celestial bodies, primarily Earth. They are designed to serve a multitude of purposes, leveraging advanced technology to fulfill various functions:

FEATURES

Communication: 

Communication satellites relay signals between different points on Earth, facilitating telecommunications, television broadcasts, internet services, and global positioning systems (GPS).

Earth Observation:

Earth observation satellites capture imagery and data about our planet's surface, atmosphere, and oceans. They aid in weather forecasting, environmental monitoring, and disasters managment

Navigation: 

Navigation satellites like GPS provide accurate positioning, navigation, and timing information globally, enabling precise location services for vehicles, smartphones, and other devices.

Scientific Research: 

 Scientific satellites explore space and conduct experiments in microgravity environments. They study celestial bodies, cosmic phenomena, and the universe's fundamental principles.

1.  Military satellites support defense and intelligence operations by providing reconnaissance, surveillance, and secure communication capabilities.

Satellites vary in size, complexity, and orbit type depending on their intended function. They are launched into space aboard rockets and operate autonomously or under remote control from ground stations. Continuous advancements in satellite technology contribute to their increasing capabilities and applications in various fields.
