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.

Lost Without Geodesy

What happens if geodesy disappears? Phones, planes, and warning systems would fail. Our cartoon “Lost Without Geodesy” shows how vital this invisible science is. Geodesy powers GNSS, enabling precise positioning, earthquake monitoring, sea level studies, and more. Without it, GNSS would drift and global systems would collapse.
