Calculate and display realtime satellite groundtracks on HTML5 map.

Input TLE (Two-Line Element Set) from file or online archive. Python script calculates subsatellite ground track for past 60 minutes, returns JSON set of lat,long tuples. HTML5/Javascript calls Python script via AJAX, updates SVG plot on world map.

Don't use this for anything serious at the moment. The results are horribly wrong.

• Unwrong it.
• Prettier graphics, SVG animation
• Access Celestrak (or other archive) and automatically grab latest TLE.
• Notification of satellite rising above observer's horizon.
• Control of steerable antenna via JSON-RPC/XML-RPC.
