Installation

To install on your own machine:

sudo apt update
sudo apt install python3-pip

git clone https://spacecruft.org/spacecruft/gnss-earth
cd gnss-earth/
# Install python setup to your taste...
# Update pip...
pip3 install --user --upgrade pip
pip3 install --user --upgrade -r requirements.txt

Need to get cesium.key from Cesium ION.

Run the app, such as: python3 beidou-earth.py

Then you can view it in a web browser. Each script has it's own port. URL will be like http://127.0.0.1:8051

If you want a more semi-permanent install with a web proxy that starts on boot, see you can do below:

There are sample Apache configs in the apache/ directory.

There are systemd files with really bad PATHs in the systemd/ directory. Copy them here: /etc/systemd/system/

Run: sudo systemctl daemon-reload

Then run systemctl start spacecruft-beidou or whatever service you want to start.

You can see what ports it is listening on (from net-tools package) ala: netstat -pant | grep py
