Which type of satellite acts as a repeater station in space?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Communication Satellite
A repeater receives a signal, amplifies it and sends it on. A communication satellite does this in space: it receives signals from a ground station, amplifies them and beams them down to another place on Earth, which carries television, telephone and internet signals over long distances.
Why the other options are incorrect
Option (2) Geo-stationary satellite — Incorrect. It names an orbit, about 36,000 km above the equator, where a satellite seems fixed in the sky; it tells where a satellite is, not what work it does.
Option (3) Polar satellite — Incorrect. It circles over the poles in a low orbit and is used mainly for weather and remote-sensing pictures.
Option (4) Sky wave satellite — Incorrect. A sky wave is a radio wave reflected back by the ionosphere, which carries signals without any satellite; no satellite goes by this name.
