What tracking program is that?

I was thinking of making my satellite icons configurable.  This way the satellite would look like the actual satellite.  Even better, I could store collada models for them and load them in place of the icon.  Oh la la, that's an idea.

If you decide to give the users the ability to input their location, them the option to provide either a single minimum elevation angle or a local map -- i.e., 360 individual minimum elevations as a function of Azimuth.  It's much easier to project this and the user is generally interested in an unobstructed LOS with respect to his/her location.

For example, there is apparently some obstruction to the south east of the Hawaiian tracking station.  If the sub-satelite point is inside the white line it's AOS.  The surface of the earth visible to the shuttle, on the other hand, is simply a red circle, just faintly visible in this image.
