People often ask me to make step-by-step explanatory videos on some of the satellite projects I present. Although I'm not yet a real expert on the subject, I've done my best to show the basics of L-band signals. These can be received with a simple small satellite dish, a software defined radio and an LNA/filter, as well as free software.

The process is a bit more complicated than VHF satellite reception (which I showed here: https://www.youtube.com/watch?vicADyjm3PBE). However, it is not very complex and the images are a little better than those available on VHF.

Here are some other great guides that can help you:

@dereksgc also has some great videos about this on his channel.

Nooelec sells an all-in-one hardware package including an antenna, SDR and LNA. That's all you need (other than a computer and software) to get started!

You can also purchase parts individually and make your own antenna. Personally, I like the RTL-SDR blog series on software defined radios:

If you purchase an SDR separately or already own one, you will also need a SAWbird GOES LNA:

If you already have a Wifi dish, you can modify it like this:

If you are creating your own dish, the sgcderek link above has good information. Or you can go REALLY cheap like I did with some of these projects:

Free software I use includes:

SDR: https://www.sdrpp.org/
SatDump: https://www.satdump.org/

I also use Stellarium, which isn't free and is somewhat blurry, but it's the only thing I could find for Android that gives an AR tracking view:

Websites I use for satellite research and tracking include:
