View source for Reception d'images satellites

We would like to receive satellite images from the [https://en.wikipedia.org/wiki/NOAA-18 NOAA-18] satellite.

This is a well-documented process and the most difficult part seems to be to build an antenna. The usual way to proceed is to use an RTL-SDR USB dongle and a few available software to do the signal decoding.

Robin has available the following:
* Soft-rock SDR module (to assemble).
* RTL-SDR USB dongle.

We would need to build the antenna.
