OrbitFix: GNSS Satellite Map

How does your phone know where you are? OrbitFix turns the answer into something you can see. Explore the navigation satellites above you on a 3D Earth, then follow how four satellites narrow a location down to a single point. 3D EARTH See satellites from GPS, QZSS, Galileo, GLONASS, and BeiDou in their orbits. Drag to rotate and pinch to zoom. SKY PLOT Find each satellite's direction and elevation on a simple map of the sky. POSITIONING Choose four satellites or use Auto Pick. Watch circles appear on Earth's surface and meet at one point, with a clear explanation at each step. SKY QUALITY Check a 0–100 score and PDOP value based on how satellites are spread across the sky. COMPARE CITIES Switch between your location and cities such as Tokyo, New York, London, and Sydney to see how the sky changes. SATELLITE DETAILS View available information such as generation, launch date, design life, PRN, NORAD ID, distance, and signal travel time. Satellite positions are calculated from public orbital data. iOS does not show which satellites your iPhone actually uses, so OrbitFix shows satellites above the horizon rather than the satellites used for your position. Sky quality is an estimate based on satellite geometry and does not include buildings or signal conditions. OrbitFix is for learning and exploration. Do not use it for navigation or safety-critical decisions.
