Opening your Tuduni experience…
Discover catalog-based spacecraft motion around Earth. Search a constellation, follow an orbit, inspect a sourced model, and turn the view into a video.
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.
Compare low, medium and high Earth orbits, study ground tracks and explore what an observer can see. Public catalogs are incomplete and positions are predictions from published mean elements.
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.
