Opening your Tuduni experience…
Follow land, ocean and environmental monitoring missions. Explore selected official NASA Landsat models and catalog-derived trajectories.
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.
Earth-observation platforms revisit the planet to record long-term changes. A ground track marks the sub-satellite point, not the exact image footprint or instrument pointing.
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.
