Results¶

Finally, several receiving pictures can be seen below. The first imagen of all sequences is the original received image from the satellite; thereafter, all the others are modify after being customized by some filters of the WXtoimg software in order to emphasize some parameters such as the colour or the thermal effect.

The time when the satellites pass a fixed point on Earth varies slightly every day. From Toulouse we can see that the satellites pass according to the sequence: Satellite 19, 18 and 15. In order to probe the antenna, the first day was taking into account the satellite 15 due to the satellite 19 and 18 had already passed at that moment. The operating frequency of this satellite is 137. XX MHz. So for being close to the operating frequency of the designed antenna, as it can be seen in the images below, a good reception of the image is achieved although this has an inferior quality compared to what will be shown later.
