Satellite Laser Ranging – How SLR Powers Geodesy

Discover Satellite Laser Ranging (SLR) – lasers from ground stations measure satellite and Moon positions with millimeter precision. SLR supports the Terrestrial Reference Frame, tracks Earth rotation, tectonic motion, improves gravity and sea level models, and tests relativity. Explore the science behind these precision measurements in our Geodesy Cartoon.
