Opening your Tuduni experience…
Explore the ISS orbit, observer geometry and an official NASA spacecraft model. Inspect the epoch of the orbit prediction before planning a sighting.
Markers and spacecraft scale are exaggerated. SGP4 predicts position, not live telemetry or spacecraft attitude. Drag to orbit, middle-drag to pan, scroll to zoom. Only selected paths are drawn.
A crewed orbital research platform operated by an international partnership. Its orbit changes with drag, reboosts and operations; a published element set cannot predict those future maneuvers.
Choose an observer location, compare orbital classes, inspect a ground track, change UTC, and follow a selected spacecraft. Save a view after signing in or capture a video using your plan's existing export limits.
CelesTrak's public OMM-compatible GP data is centrally cached. Element epochs and snapshot dates stay visible. Positions are SGP4 predictions, and a spacecraft model's authenticity is separately labelled.
