Viewing Satellite Close Approaches With Google Earth

Software Architecture

collisionThis is a web-based Google Earth visualization I designed for satellite close approaches. The system is comprised of a PHP script that ingests two satellite ephemeris files and generates a KML file. Each time step is a new GXTrack entry, so as the KML file loads the two satellites animate along their orbit path. Uncertainty is represented by 3D sphere objects that are dynamically sized. The KML file can be downloaded for offline viewing in Google Earth.
