[Ground-station] Link budget

[Thomas Savarino]

I’d like to hear more about your Golang work and why you use that.

The main reason was that I am not an experienced python person (yet) but I have contributed in the past  to some Matlab utilities for RF work that were converted to executables in the end. Matlab isn't open source, but Octave is, and it was one of the original open engineering tools. It's been around for 20 plus years and has good community support. I was thinking that a link budget and propagation "Toolbox" for Octave might be a nice thing to have for the community.

Numpy probably has most if not all of the functions you’ll need.
