About this app
This app will notify you if you can see the ISS (International Space Station) when it flies overhead.
The app retrieves orbital data (Two Line Elements) for the ISS from the internet and uses your GPS coordinates to determine when it will be visible from your location.
The orbit is calculated using the open source Orekit space dynamics library.
