Live NORAD catalogue tracking with SGP4 propagation. Cold War-era radar scope aesthetic. Native on iPad in every orientation. Astronomy from AstroEngine, measured against NASA JPL.

Satellite tracker app for iPhone and iPad. Track thousands of objects from the NORAD space catalogue in real time with SGP4 propagation. Cold War radar scope aesthetic — like watching BMEWS from Fylingdales. Runs natively on iPad in every orientation, the radar scope grown to fill the screen. Its astronomy comes from AstroEngine, the on-device engine shared across our sky apps and measured against NASA JPL Horizons.
