ORBITAL INTELLIGENCE
Observer.
Predict geometric satellite passes above your observing location.
Coordinates stay in this browser. Height is measured above the WGS84 ellipsoid; if unavailable, zero is used as an explicit approximation.

SGP4 predicts line of sight, not whether a satellite will be visible. No weather, brightness, terrain or atmospheric-refraction estimate is implied. Elements older than 72 hours at the prediction horizon are rejected.
