How do satellites improve life?

Os satélites fornecem near real-time data for monitoring farms.. Remote sensing satellites provide us with detailed information and rainfall assessments. This allows farmers to better manage their harvest and livestock. Giving us the tastiest Australian produce on our plates.

What is satellite and how it works? A satellite is basically a self-contained communications system with the ability to receive signals from Earth and to retransmit those signals back with the use of a transponder—an integrated receiver and transmitter of radio signals.

How is satellite used for communication for kids? A communications satellite 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.

Why are the satellites so important? They allow us to make cellular phone calls from long distances. They provide us with a global positioning system (GPS) so that we know exactly where we are and we can find directions to anywhere we want to go. They circle the earth and relay weather conditions and forecasts.
