Raspberry PI operating system

I’m using Raspbian as it have full support for Raspberry PI, simple package manager and it’s pretty stable

Automatic install

1. Update repositories and install git

sudo apt update
sudo apt install git

2. Clone this repository on your home directory

cd $HOME
git clone https://github.com/reynico/raspberry-noaa.git
cd raspberry-noaa

2. Run ./install.sh. You will be asked for your ground station lat/lon position.
3. If you want automatic Twitter posting, see: Set your Twitter credentials

This is pretty much the entire setup. If you are interested about the behind of scenes please check the following section
