A live 3D data visualisation of satellites orbiting Earth. TLE data from CelesTrak is parsed via SGPdotNET to compute real-time positions and predicted orbits in a Unity scene.
Main satellite view interface with a satellite selected
Wider view showing geostationary orbits
Displaying rosetta orbit path
Displaying recently launched satellites (mainly Starlink satellites)
Showing a shorter orbit path

Displayed at Falmouth University Expo 2025How it works:
NORAD GP element sets (TLE) are fetched from celestrak.org and converted into coordinates/altitudes with the SGPdotNET C# library. Using Unity, these are visualised as satellite instances over a 3D Earth, with click-through details and orbit path prediction.
Usage:
WASD or arrow keys for camera movement, click satellites for details, and use the time controls (speed up, pause, reverse) to explore trajectories.
