VELA - Starlink ISS Tracker

VELA - Satellite Pass Alerts

See the next Starlink train or satellite pass over your head, with a live countdown and exactly where to look.

VELA is a precision instrument for spotting satellites with the naked eye. Every number in the app is computed on your device from the live orbital catalog. No estimates, no invented data, no accounts.

TONIGHT AT A GLANCE
- The next visible pass over your exact location, with a live countdown
- A departures board of upcoming passes for the night ahead
- Entry and exit directions, peak altitude, duration and sunlit fraction for every pass
- A rotating ground track globe showing where the satellite is right now, over real coastlines

LIVE MODE
When the countdown hits zero, VELA becomes an instrument. The compass rotates with your phone, a guide arrow points your eyes to the satellite, and haptic pulses mark its climb. Follow the pass from horizon to horizon in real time.

STARLINK TRAIN DETECTION
When a fresh batch of Starlink satellites appears in the orbital catalog, VELA detects the new train and shows its first visible pass over you, so you can catch the famous string of lights before it disperses.
