Every Starlink satellite, live on a beautiful 3D globe. Space tracks the entire Starlink constellation in real time — more than 10,000 satellites rendered as a living shell around a realistic Earth with day and night sides, city lights, and the real positions of the sun, moon, and planets in the sky. THE CONSTELLATION, LIVE • 10,000+ Starlink satellites, positions computed from live SpaceX orbital data • Smooth real-time motion — watch trains of newly launched satellites sweep across the globe • Realistic Earth with a true day/night terminator and glowing night cities KNOW EVERY SATELLITE • Tap any satellite for its live position, generation, NORAD ID, and launch object • Filter the fleet by generation — from the earliest v0.9 birds to the latest v2 fleet • See 250 Starlink gateway ground stations worldwide, plus your own spot under the shell BEYOND EARTH • Pinch out to leave Earth and open the solar system • Visit every planet from Mercury to Neptune — real positions and gorgeous close-ups • Live distance gauges and Starship travel-time estimates for every destination THE SPACEX PULSE • Upcoming Falcon 9 and Starship launches with pads, orbits, and mission details • Jump straight to the launch stream • SpaceX stock price and market cap at a glance Whether you're a space enthusiast, a Starlink customer curious about what's overhead, or you simply want the most beautiful globe on the App Store — Space makes the sky feel alive.

D2CTracker

D2C Tracker helps you explore Direct-to-Cell satellite coverage from your current location. View compatible satellites on an interactive 3D globe, sky dome, or horizon display. The app uses current orbital data, local terrain, RF geometry, and satellite motion to estimate which satellite is most likely to provide service. Features include: - Live 3D globe and local sky views - Likely serving-satellite estimates - Elevation, azimuth, range, Doppler, path-loss, and uplink estimates - Offline state terrain packs for line-of-sight modeling - Background location tracking and Live Activities - Data-freshness and terrain-coverage indicators - Optional low-traffic Internet link diagnostics - GPS and manual-location support - On-device orbital and terrain calculations D2C Tracker is independent software and is not affiliated with or endorsed by SpaceX, Starlink, any wireless carrier, or CelesTrak. Satellite identity, serving probability, RF performance, and connectivity quality are estimates, not modem-confirmed measurements and should not be used for navigation or safety-critical decisions.
