Opening your Tuduni experience…
Inspect GPS spacecraft in medium Earth orbit and compare inclination, orbital periods and ground tracks.
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.
Navigation satellites broadcast timing and orbit information. This educational SGP4 view is not a receiver navigation solution or a substitute for broadcast ephemerides.
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.
