Earth Observation FAQs

What is a satellite?

A satellite is an object that goes around, or orbits, a larger object, such as a planet. While there are natural satellites like the Moon orbiting the Earth. Hundreds of man-made satellites also orbit the Earth. Communications antennas, radio receives and transmitters enable the satellite to communicate with a ground station, called a command centre. Environmental satellites transmit data as numbers to a computer on Earth, which translates this digital data into images.
