The Sun is the main energy source for satellites , which is why all satellites have solar panel arrays mounted on them. Each array contains thousands of small solar cells which are made of silicon – a material that allows sunlight to be turned into electrical current.
Read moreHow do satellites move in space?
Even when satellites are thousands of miles away, Earth’s gravity still tugs on them . Gravity—combined with the satellite’s momentum from its launch into space—cause the satellite to go into orbit above Earth, instead of falling back down to the ground.
Read moreWhat is satellite communication and how does it work?
Satellites communicate by using radio waves to send signals to the antennas on the Earth . The antennas then capture those signals and process the information coming from those signals.
Read moreWhat is the example of satellite communication?
Telephone, radio, television, internet, and military applications use satellite communications.
Read moreWhat type of communication is a satellite used for?
Satellites provide in-flight phone communications on airplanes, and are often the main conduit of voice communication for rural areas and areas where phone lines are damaged after a disaster. Satellites also provide the primary timing source for cell phones and pagers.
