Direct-broadcast satellite (DBS) is a type of artificial satellite which usually sends satellite television signals for home reception.

This is a list of satellites in geosynchronous orbit. 

These satellites are commonly used for communication purposes, such as radio and television networks, backhaul, and direct broadcast.

The type of satellite television which uses direct-broadcast satellites is known as direct-broadcast satellite television (DBSTV) or direct-to-home television (DTHTV).

These satellite orbits around the earth. 

The act of orbiting, and the work of artificial man made satellites were designed to imitate the natural satellite known as the moon.

As moon the orbits around the earth, it also scatters forth light (moon light) which plays the role of developing the natural resources which are concealed in the earth, sustaining radar communication frequencies, and also improving the functioning abilities of the artificial satellites.

While the artificial man made satellite, their role is to broadcast telecommunication signals as they orbit around in space.
