ISS Observer

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.

A piece of garbage. It states that initial values of "pass times" (which no one asked for) are computed for year 1969, when the ISS was only in the minds of the likes of Arthur C. Clarke & fans: COMPLETELY ABSURD. And then it makes you wait until some weird "flyover computations" are done... which seem to take FOREVER. UNINSTALLED IMMEDIATELY!
