What's Above Me?

This app tracks satellites using TLE (Two-Line Element) orbital data from Celestrak and propagates their orbits in real time using SGP4.

The cone angle defines a viewing cone centered on your zenith (straight up). A 1° cone includes satellites between 89–90° elevation (nearly overhead), while 90° includes the entire visible sky above the horizon.

The 2D map shows ground projection circles corresponding to satellites at different altitudes. For the same elevation angle, higher-altitude satellites project farther from your location on the ground.

The 3D globe displays satellites in space around Earth. Your position is shown in yellow, and satellites are placed using their calculated azimuth and elevation relative to you.
