Live GNSS Health & Sky
Free · In‑App Purchases
“Transit satellites are helping our ships at sea to steer a safer course.” —President Kennedy, 1962. Today 100+ navigation satellites orbit Earth. Watch every one.
Integrity Satellite Monitor turns live GNSS observations into a clear picture of the navigation satellites above you.
MONITOR CONSTELLATION HEALTH
Follow GPS, Galileo, GLONASS, BeiDou, and other GNSS systems using observations from the independent Galmon ground-station network. See live satellite and signal counts, constellation health, sky visibility, timing offsets, and reported anomalies.
EXPLORE THE SYSTEM
Move through an interactive 3D Metal globe with Earth, the Moon, planets, satellites, constellations, and a detailed star catalog. Download higher-resolution planet textures at no charge.
SEE THE SKY AROUND YOU
On supported iPhone and iPad models, use AR to place satellites, planets, and stars against the live sky. Location, camera, and motion access are optional and used only for features that need them.
BUILT FOR PRIVACY
No account is required. Your location, waypoints, bookmarks, and preferences stay on your device. The app contains no advertising, analytics, or third-party tracking.
Every in-app feature is free. Optional support subscriptions fund continued development and provide supporter service benefits; they do not unlock app functionality.
Available on iPhone, iPad, Mac, Apple TV, and Apple Watch.
GNSS observations are sourced from the Galmon community monitoring network.
