Aviation & Flying
Know exactly where you are at 35,000 feet.
Watch your GPS position, altitude, and ground speed update in real time from your seat — no overpriced cabin Wi-Fi required.
A mountain range below. A coastline on the horizon. Where exactly are you?
You're three hours into a transatlantic flight. The seatback screen is broken, the cabin Wi-Fi wants $19.99, and all you know is you're "somewhere over the Atlantic." Out the window, you spot an island chain — but which one?
GPS signals travel from satellites at about 20,200 km altitude down to Earth. Your airplane cruises at roughly 10–12 km — barely a rounding error for signals that already crossed 20,000 km of space. Aircraft windows allow enough signal through for your phone to compute a position, especially from a window seat where your iPhone has a direct line to the sky.
SkyLocation shows your live coordinates, ground speed (many passengers are amazed to see 900+ km/h), and altitude in feet or meters. You can identify that island chain, watch yourself cross the prime meridian, or figure out exactly when you'll cross into a new time zone — all without spending a cent on in-flight Wi-Fi.
Built for aviation & flying
Every feature designed for your specific needs.
Live Position at Cruise Altitude
Watch coordinates tick as you cross continents, oceans, and borders. Identify landmarks, coastlines, and mountain ranges from 35,000 feet.
Ground Speed in Real Time
See your true ground speed — often 850–950 km/h — and impress your seatmate. Toggle between km/h, mph, and knots.
Altitude Above Sea Level
Track your cruising altitude, see the descent begin, and watch altitude drop as you approach landing. Choose feet or meters.
Window Seat Advantage
GPS reception is strongest near the window where your phone has a direct line to the sky. SkyLocation shows signal accuracy so you know when the fix is solid.
No Wi-Fi Fee Required
SkyLocation uses satellite signals, not the airplane's internet. Save your money — GPS positioning is completely free and works in airplane mode.
Country & Region Context
When reverse geocoding data is cached, see which country or region you're currently flying over. Coordinates are always available regardless.
“I use SkyLocation on every flight. Watching the coordinates change as we crossed from Europe into Africa was fascinating — I could pinpoint the exact moment we flew over the Strait of Gibraltar. Way better than paying $20 for cabin Wi-Fi just to check a flight tracker.”
