OrbTrack, View The World Above

Open source: https://github.com/calsurferpunk/Orbtrack Allows you to discover where many of the objects above earth are at any time and place. Satellites, rocket bodies, debris, planets, the moon, the international space station, constellations, and some stars, can be viewed at the time and place of your choosing (past, present, and future). You can view actual position locations using your phone's camera, calculate coordinates and see them on a map, playback future/past position events, or even save the data to be used somewhere else. Does not require an internet connection to perform calculations and no personal data is ever stored outside of your device. Features include: -No advertisements or fees (completely free) -Augmented camera view with outlines and travel paths (*requires calibration, compass, and accelerometer) -3d globe view of current locations -Calculating positions/coordinates at any time and place -Searching a vast catalog of satellites, rocket bodies, and debris to track -Information retrieval of nearly all objects -Saving data locally and/or to some cloud based storage solutions -Automatic updating of satellite TLE's (configurable) -Multiple languages (currently English and Spanish) -Many options for personalization (themes, displays, and more) -No internet connection required for calculations (can be run anywhere as long as a location and time are available) Special thanks to Space-Track, Celestrak, N2YO, and NASA for their continued satellite information. Also thanks to Lee Mette from the Noun Project for the satellite icon, Moozarov for the planet icons from the to infinity and beyond set, and map tiles by Stamen Design.
