Welcome! This tool lets you explore live satellite orbits in interactive 3D.

🔹 Data

• Source: CelesTrak — Two-Line Element (TLE) sets
• Update: Fresh TLEs are loaded each time you open the page (no continuous background polling)
• Accuracy: Positions are computed with the SGP4 model — real satellites may drift slightly due to maneuvers or drag

• Mouse / Touch: drag to rotate, scroll/pinch to zoom, right-drag to pan
• Hover: show orbit + satellite details
• Click: select / deselect a satellite
• Alt + hover Earth: view local time under cursor
• Double-Alt: pin a ground-track pass
• Esc: clear pins or close panels
• Keyboard:
  • Space: play / pause time
  • . (dot): step forward 1 second
  • O: toggle orbit lines
  • S: toggle shadows
  • L: toggle states/provinces

🔹 Features

• Search satellites by name or NORAD ID
• Browse all satellite pages
