For once, let’s allow ourselves to have our heads in the clouds, and even a little above. Did you know that there are several types of satellites? Of course I do! Satellites can be natural or artificial. But even more so, two types of artificial satellites can be distinguished: The scrolling satellites (which we will talk about again not to worry) and the Geostationary satellites that we are interested in today.
The geostationary satellite
A geostationary satellite is a satellite that rotates around the Earth in exactly 24 hours and always remains at the zenith (i.e. just above) of the same place. To do so, this satellite must be placed at the level of the Earth’s equator and at an altitude of 36,000 km.
What are they used for?
Telecommunications or television satellites are placed in geostationary orbit because it allows information to be transmitted or received using antennas with a fixed position. For example, when our technicians install you with a satellite Internet reception antenna (a dish) on your house, it must always be oriented in the same direction (unless you want to change satellites) and always be tilted at the same angle (depending on where you live), in order to target the communication satellites that are all above the equator. Now think about it when you enjoy satellite internet wherever there is sky!
