Satellite Photo-bomb Simulator

This tool reconstructs a sky or earth image that is potentially crossed by one or more satellites. After setting the location, shot details, and the exact UTC time, press Start to run visualizer for the camera's field of view. Satellites found to be present or crossing at the time time period specified will be listed and the trails they can make will show. Note that in reality satellites are nearly invisible unless sun-lit against a night sky. The final image displays the star field and satellite paths even if the UTC time is during the day. Past time inputs correctly use historical instead of current data.
