OpenSky Track

OpenSky Track helps you understand your position even when reception is weak, coverage is limited, or you are completely offline.

Perfect for ✈️ flights, 🥾 hiking, 🚗 road trips and remote areas, it shows not just where you are, but how reliable your GPS/GNSS position really is — and helps guide you toward better signal when reception is weak.

See your live position, altitude, speed, accuracy and signal lock at a glance. Follow satellite acquisition in real time, explore the sky plot, and understand how your phone is building its position.

🛰️ Live satellite and signal view

Track visible satellites, satellites used for your current position, signal strength, azimuth, elevation and constellation details in real time.

📍 Understand your position quality

OpenSky Track clearly shows whether your phone is still searching, has only an approximate position, or has a stable and reliable lock.

✈️ See where you’ll be next

Estimate where you are likely to be in 30 minutes or 1 hour based on your current direction and speed. Especially useful in planes, trains and long-distance travel.

📡 Catch signal when reception is weak

Aiming guidance helps you point your device toward a better part of the sky to improve satellite visibility and recover signal more easily.

🗺️ Built to work offline

Core GNSS features work without internet, with offline world map support included. Ideal for travel, flights and places with poor or no mobile coverage.

🧭 Clear, practical and easy to read

Large readable values, a clean dashboard, dark-theme-friendly visuals, and useful satellite views make OpenSky Track easy to use in real-world conditions.

OpenSky Track is built for travelers, flight passengers, outdoor users and anyone who wants a clearer, more honest view of GPS/GNSS performance.

Not just where you are — but how well your phone knows it, and where you’re heading next.
