🌐 Orbital Regimes Explained
Low Earth Orbit
160-2,000 km
Home to the ISS, Starlink, and most Earth-observation satellites. Fast ~90-minute orbits.
Medium Earth Orbit
2,000-35,786 km
Navigation constellations like GPS, Galileo, and GLONASS operate here.
Geostationary
~35,786 km
Satellites match Earth’s rotation, appearing fixed in the sky. Communications and weather.
Highly Elliptical
Variable
Elongated orbits that dwell over high latitudes. Used for polar communications and early warning.
About This Tracker
Data Sources
- CelesTrak NORAD TLE Catalog
