Space Coordinate Tools
Satellite tracking and orbital coordinate utilities
Satellite Ground Track
Visualize satellite ground tracks on a 3D globe. Track multiple satellites with live updates.
Reference Frame Converter
Convert coordinates between ECI (TEME), ECEF, and Geodetic reference frames.
Orbit Viewer
Parse TLE or OMM data and visualize satellite orbital paths on a 3D globe.
TLE to OMM Converter
Convert between TLE and OMM (KVN, XML) orbital data formats. Search satellites or enter custom data.
Data Sources
Space-Track.org
Official NORAD two-line element sets updated daily.
SGP4 Propagation
Industry-standard algorithm for satellite position prediction.
Real-Time Updates
Position calculations run client-side every second.
Supported Reference Frames
ECI (TEME)
Earth-Centered Inertial in True Equator Mean Equinox. Standard frame for TLE propagation.
ECEF (ITRF)
Earth-Centered Earth-Fixed. Co-rotates with Earth, used by GPS.
Geodetic
Latitude, Longitude, and Altitude above WGS84 ellipsoid.
