Add ISS to list of objects #18

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I would like to be able to track the ISS using this application. Given that the 
moon exits, I take it is possible to add earth-orbiting stellar objects to the 
list of objects in the app.

Common request. We had some half-written code to do this.

Its somewhat straightforward to calculate, but the orbital parameters of the ISS periodically change. To correctly implement this, we need a way to grab the latest data. Also note, the window to see the ISS is very short, so we need to be very accurate with our calculations. I think it can be done, but it does break the "don't need the internet" requirement of Sky Map.

Usually, apps like "ISS detector" use other sites like http://www.heavens-above.com/ for the ISS. Is it possible to store the data downloaded from that site to use it offline?

If their terms and conditions allow it, sure. We've been thinking about supporting more objects (esp. those involving dynamic data), revamping our data model etc for ages. It'll happen at some point, but it'd be a pity to hold off on much sought after features like this indefinitely just to avoid a future refactoring.

We'd want to be considerate of their bandwidth. I think it's unlikely, but we'd want to make sure that any update containing that code didn't ddos them. So no objections from a Sky Map point of view, just a good neighbor point of view.
