NOAA weather satellite image signal capture (part I)

Here is my last experiment, partially completed. I said "partially" because I recived not a perfect result as I'd would prefer.

Start!

There are three NOAA satellites that spread their signal all over the world in broadcast without any form of cryptography: I can simply obtain this signal using an antenna, a receiver and a PC.

Receipt

What do I need? This is the necessary hardware list:

• a couple of cupper wires;
• antenna cable (including the two end points);
• paper adhesive tape (or made of another neutral material);
• A DAB + SDR + FM RTL2832U + R820T2 receiver (you can purchase it  right here: https://www.amazon.it/gp/product/B013Q94CT6/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1);

Receiver (you have to plug it in the PC).

• an adapter DVB-T DVBT coaxial RF MCX Antenna TV via cavo (you can purchase it right here: https://www.amazon.it/gp/product/B00H3CS4BK/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1);

Use this cable to connect you receiver to the antenna cable.

• a PC.

Bash: download data from NOAA #1

It's going to start a new adventure: download data directly from NOAA (National Oceanic and Atmospheric Administration).

Few rows written in bash useful to download data from the NOAA to obtain information about weather for the next days: a lot of data.

Here is the github project named ngrib:
