Decoding Signals from the Sky
|
|
The first successful attempt of putting an artificial satellite in orbit around the Earth was Sputnik 1, launched in 1957 by the Soviet Union. Nowadays, about 3 500 artificial satellites are in full operation around the Earth.
Artificial satellites allow us to maintain communication between different places in our planet, study the meteorological conditions of a region, as well as observe other planets in the Solar System, the Sun and other stars in our galaxy and other galaxies. They have been a key instrument for the development of the Space sector.
In order to receive information from a satellite, firstly, its trajectory must be tracked. Once it is in a visible region for the receiving antenna, a signal can be received. This signal is then decoded to visualise the information.

In this laboratory, students study the way communication is made with a satellite by tracking its location, decoding a signal from a satellite and visualising the image that is built. They explore and interpret the information that can be extracted from a weather image.
